Q8 of 56 Page 135

If ΔABC ~ ΔDEF and AB = 10 cm, DE = 8 cm then the ratio of area of ΔABC and area of ΔDEF will be:

To find: Ratio of Area of Similar triangles

Given: Their corresponding sides AB = 10 cm and DE = 8 cm 

For similar triangles ABC & DEF, the ratio of the areas of two similar triangles is equal to the ratio of squares of their corresponding sides.

For both triangles there corresponding sides will be AB and DE





Hence, Ratio of area of triangles ABC anf DEF is 25:16
