That's what I got...but clearly it's not a parallelogram, so what am I doing wrong, and what do I need to do differently?

^^thats how it should look. graphing is a very good idea, but u dont need to graph to solve this problem.

u figured how to work the problem ?

BTW, someone told me the answer to this problem was 12. Are they right? I got 4.2... √((3) – (0))² + ((0) – (3))² = √3² + 3² = √9 + 9 = √18 ≈ 4.2

yes, I did

working on the second question now

Are you given instructions that u need to work it by graphing ?
 4 months ago

HourglassMage Group TitleBest ResponseYou've already chosen the best response.1
Yeah, they taught graphing and the distance formula and whatnot
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
no, i mean did the instructions specifically ask u to do this by graphing ?
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
cuz, u should NOT use graphing unless the instructions say so
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
the common/regular way to work this problem is by finding lengths of sides using `distance formula` and the slopes of sides using `slope formula`
 4 months ago

HourglassMage Group TitleBest ResponseYou've already chosen the best response.1
Those were the directions they gave me
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
cool :) then you're right ! they want u work it by graphing
 4 months ago

HourglassMage Group TitleBest ResponseYou've already chosen the best response.1
Given that they gave me the graph, I would assume that they want me to solve it by graphing, but I also used the distance formula to find the lengths of the sides
 4 months ago

HourglassMage Group TitleBest ResponseYou've already chosen the best response.1
ok :)
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
good :) your length of sides, and perimeter are correct. but Area is wrong.
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
squaring sides will not give u Area for a rhombus.

ohh..just looked it up A  diagonal x diagonal/2

Area of rhombus = \(\frac{1}{2} d_1 d_2\)
 4 months ago

HourglassMage Group TitleBest ResponseYou've already chosen the best response.1
Great, now I have to find the diagonals, lol
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
its easy from graph

horizontal diagonal = 33 = 6 vertical diagonal = 33 = 6
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
So, Area = \(\frac{1}{2} d_1 d_2 = \frac{1}{2} 6*6 = 18\)

And that makes the given rhombus a SQUARE !
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
so the given parallelogram is not just a rhombus, its also a SQUARE !
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
for the `type of parallelogram `, you should say that its a `square`
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
if that makes any sense..

HourglassMage Group TitleBest ResponseYou've already chosen the best response.1
The parallelogram is a rhombus and a square?
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
just say its a SQUARE !
 4 months ago

HourglassMage Group TitleBest ResponseYou've already chosen the best response.1
rhomus: all equal sides, two pairs of equal angles square: equal sides, equal angles

HourglassMage Group TitleBest ResponseYou've already chosen the best response.1
oh, ok

Does that change my equation for the area, then?
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
all squares are parallelograms all squares are rhombuses all squares are rectangles all squares are quadrilaterals

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
a square is many things

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
yes it will change ur formula, but the answer will be same

HourglassMage Group TitleBest ResponseYou've already chosen the best response.1
I see that, lol

how do you find the diagonals inside a rhombus?
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
use the distance formula
 4 months ago

HourglassMage Group TitleBest ResponseYou've already chosen the best response.1
oh, its the same process, ok, hold on
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
ok, i presume u knw what a diagonal is :)
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
it just connects the opposite vertices

^^those two line segments joining opposite vertices are diagonals
 4 months ago

HourglassMage Group TitleBest ResponseYou've already chosen the best response.1
Is that correct? I found it odd that I got the same area for #1 and #2...but maybe that's just a coincidence
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
diagonals are not equal in rhombus
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
so u need to calculate the 2nd diagonal also using distance formula
 4 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
and then use the area of rhombus formula : Area = \(\frac{1}{2}d_1 d_2\)
