Best ResponseYou've already chosen the best response.1That'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?

Best ResponseYou've already chosen the best response.1^^thats how it should look. graphing is a very good idea, but u dont need to graph to solve this problem.

Best ResponseYou've already chosen the best response.1u figured how to work the problem ?

Best ResponseYou've already chosen the best response.1BTW, 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

Best ResponseYou've already chosen the best response.1working on the second question now

ganeshie8

Best ResponseYou've already chosen the best response.1Are you given instructions that u need to work it by graphing ?

HourglassMage

Best ResponseYou've already chosen the best response.1Yeah, they taught graphing and the distance formula and whatnot

ganeshie8

Best ResponseYou've already chosen the best response.1no, i mean did the instructions specifically ask u to do this by graphing ?

ganeshie8

Best ResponseYou've already chosen the best response.1cuz, u should NOT use graphing unless the instructions say so

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

Best ResponseYou've already chosen the best response.1Those were the directions they gave me

Best ResponseYou've already chosen the best response.1cool :) then you're right ! they want u work it by graphing

HourglassMage

Best ResponseYou've already chosen the best response.1Given 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

ganeshie8

Best ResponseYou've already chosen the best response.1good :) your length of sides, and perimeter are correct. but Area is wrong.

ganeshie8

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

Best ResponseYou've already chosen the best response.1Area of rhombus = \(\frac{1}{2} d_1 d_2\)

Best ResponseYou've already chosen the best response.1Great, now I have to find the diagonals, lol

ganeshie8

Best ResponseYou've already chosen the best response.1horizontal diagonal = 33 = 6 vertical diagonal = 33 = 6

ganeshie8

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

Best ResponseYou've already chosen the best response.1And that makes the given rhombus a SQUARE !

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

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

ganeshie8

Best ResponseYou've already chosen the best response.1if that makes any sense..

HourglassMage

Best ResponseYou've already chosen the best response.1The parallelogram is a rhombus and a square?

ganeshie8
 8 months ago
Best ResponseYou've already chosen the best response.1just say its a SQUARE !

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

Best ResponseYou've already chosen the best response.1Does that change my equation for the area, then?

ganeshie8

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

ganeshie8

Best ResponseYou've already chosen the best response.1a square is many things

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

Best ResponseYou've already chosen the best response.1how do you find the diagonals inside a rhombus?

ganeshie8

Best ResponseYou've already chosen the best response.1use the distance formula

HourglassMage

Best ResponseYou've already chosen the best response.1oh, its the same process, ok, hold on

ganeshie8

Best ResponseYou've already chosen the best response.1ok, i presume u knw what a diagonal is :)

Best ResponseYou've already chosen the best response.1^^those two line segments joining opposite vertices are diagonals

HourglassMage

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

ganeshie8
 8 months ago
Best ResponseYou've already chosen the best response.1diagonals are not equal in rhombus

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

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