Question

I need help please I don’t know how to solve these

Answer 1

2:

You're finding perimeters so you're basically adding up all the sides.

44 + 36 + 11 +9 = 100

P(triangle BDE) = 100

4:

triangle XYZ is double the size of triangle RST

the constant of proportionality is 2

This means that ZX will be 12 , ZY will be 26 , and XY will be 17.4

Add them together, and you get 55.4

P(triangle XYZ) = 55.4
