Question

Polygons P (side is 2) and P (side is 5) are similar polygons

a)if the perimeter of P is 10, what is the perimeter of P?

b) if the area of P is 30 what is the area of P

Answer 1

the ratio is 5/2
if the perimeter of first P is 10, perimeter of second P is 10*(5/2)=25

if the area of first P is 30, area of second P is 30*(5/2)^2= 187.5
