Question

The perimeters of two similar triangles ∆ABC and ∆PQR are 35cm and 45cm
respectively, then the ratio of the areas of the two triangles will be?

Answer 1

First divide

35/45=7/9

Then double the value since one side is 7/9 if we double it we will 3 side of the triangle

So the ratio of the area of 2 triangle is

7^2÷9^2= 49/81

49:81

Hope it helps
