Question

The corresponding sides of two similar triangles ABC & DEF are BC = 9.1 cm &
EF = 6.5 cm. If the perimeter of ∆DEF is 25 cm, find the perimeter of ∆ABC.​

Answer 1

Step-by-step explanation:

Therefore, their corresponding sides will be proportional. Also, the ratio of the perimeters of similar triangles is same as the ratio of their corresponding sides. Thus, the perimeter of ΔABC is 35 cm.

Answer 2

Step-by-step explanation:

It is given that ∆ ABC - ∆ DEF.

Therefore, their corresponding sides will be proportional.

Also, the ratio of the perimeters of similar triangles is same as the ratio of their corresponding sides. Also, the ratio of the perimeters of similar triangles is same as the ratio of their corresponding sides.
