to find the perimeter of given shape, you need to find out sides first

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
perimeter = sum of all sides

know how to find the length of sides on coordinate plane ?
 7 months ago

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
distance formula ?
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
yes, but for that u need to figure out coordinates of points and plug them in the formula... which is a pain... and u need to do it for 5 times... since u have 5 sides
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
there is a simpler way to do this, which uses the distance formula in disguise...
 7 months ago

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
whats the simpler way ?
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
use pythagorean theorem : that red side = \(\sqrt{2^2+6^2} = \sqrt{40}\)
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
this is exact same as distance formula, but this is felt simple because, you're not plugging in the coordinates... instead you're just counting the number of grids...
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
use whichever u feel is easy...
 7 months ago

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
how did u solve that ^ ... like how did u get 40 ?
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
the goal is to find the length of all sides and add up
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
did u get how I got : red side = \(\sqrt{2^2+6^2} \)
 7 months ago

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
i know how u got the 2 and the 6... just not the 40 ...
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
oh cool :) ive just skipped a step : red side = \(\sqrt{2^2+6^2} = \sqrt{4+36} = ?\)

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
ohhh ok

find the lengths of remaining sides in any way u wish, and add them all up
 7 months ago

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
for pt it would be 4^2 + 10^2
 7 months ago

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
which is 116
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
Yes ! dont forget the sqrt
 7 months ago

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
ok...
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
\(PT^2 = 4^2 + 10^2\) \(PT = \sqrt{4^2 + 10^2} = \sqrt{116}\)

TS is 7

how do i do SR O.o
 7 months ago

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
50 ok..

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
*sqrt...
 7 months ago

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
right... lol and then the last side is sqrt 61 ?
 7 months ago

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
do i add them all ?
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
yup ! perimeter = length around a shape = sum of all sides
 7 months ago

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
sqrt 274
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
you cannot add radicals like that

\(\large \sqrt{a} + \sqrt{b} + \sqrt{c} ~ \ne ~ \sqrt{a + b+ c}\)

hm i got 60 ;/
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
You got : \(QP = \sqrt{40}\) \(PT = \sqrt{116}\) \(TS = 7\) \(SR = \sqrt{50}\) \(RQ = \sqrt{61}\)
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
plug each sqrt in ur calcualtor and add them all
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
\(QP = \sqrt{40} = \color{red}{6.32}\) \(PT = \sqrt{116} = \color{red}{10.77}\) \(TS = 7 = \color{red}{7}\) \(SR = \sqrt{50} = \color{red}{7.07}\) \(RQ = \sqrt{61} = \color{red}{7.81}\)  perimeter = \(\color{Red}{?}\)

38. 97

wolfram says the same : http://www.wolframalpha.com/input/?i=sqrt%2840%29+%2B+sqrt%28116%29+%2B+7+%2B+sqrt%2850%29+%2B+sqrt%2861%29

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
so should i put 39 ?
 7 months ago

Gabylovesyou Group TitleBest ResponseYou've already chosen the best response.1
or try it the long way to double check
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
rounding it becomes : \(38.97 \approx 39\)
 7 months ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.2
Nope, both are one and same... you may try for practice if u want maybe :)

okay :) thank you!
