Question

triangles abc and def are similar. The length of each side of triangle abc is 8 times the length of each corresponding side of triangle def. How many times greater is the area of triangle abc than the area of triangle def

Answer 1

64

Explanation:

If each side length is multiplied by 8, the product of two side lengths will be multiplied by 8×8 = 64.

Area is proportional to the product of two side lengths, so will be multiplied by 64.
