Question

Find the perimeter of the image below:
37 units
38 units
39 units
40 units

Answer 1

perimeter is the sum of the length of all sides of a polygon

Answer 2

i know that

Answer 3

I just don't understand how I am supposed to find it

Answer 4

you should find the length of line segment PT, ST, RS, and QP using the formula for length/distance
\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Answer 5

can you do it with me?

Answer 6

i can try, if i still have time :)

so first, let's look do the distance of line segment PT
P has a point (-2,11) --> \((x_1, y_1)\)
T has a point (8,7) ---> \((x_2,y_2)\)

try plugging this points to the formula :)

Answer 7

So would it be 22?

Answer 8

hmm.. i got a different answer for that
\(d=\sqrt{(8+2)^2+(7-11)^2}\)

Answer 9

26?
