# If and are two triangles such that , then Area (): Area () =A. 2 : 5B. 4 : 25C. 4 : 15D. 8 : 125

Given ΔABC and ΔDEF are two triangles such that

We know that if two triangles are similar then their sides are proportional.

Since , ΔABC and ΔDEF are similar.

We know that the ratio of areas of two similar triangles is equal to the square of the ratio of their corresponding sides.

ar (ΔABC): ar (ΔDEF) = 4: 25
