Question

Perimeters of two similar triangles ∆abc and ∆pqr are 35cm and 45cm respectively, then the ratio of the areas of the two triangles are

Answer 1

Answer: The ratio= 35/45 if triangle ABC/triangle PQR

=> 7/9

if trianglePQR/ triangle ABC then the ratio is 45/35 i.e; 9/7

Answer 2

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
