Answer 3

What you have to know is that those figures are similar.

Answer 4

yeah i know that

Answer 5

That means that corresponding sides have equal ratios. That means we can write proportions that allow us to find x, y, and z

Answer 6

When we find those values, we can find the perimeter by adding all the sides.

Answer 7

can you help me find it please

Answer 8

Do you know all the sides?

Answer 9

\[\frac{AI}{WE}=\frac{BN}{PQ}\]

Answer 10

AI=12.5
WE=2x+1
BN=10
PQ=4
Can you substitute those values into the proportion I wrote?

Answer 11

Hello. Are you there?
