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

Question

Philoid · Accepted Answer

Given that, ∆ABC ∼ ∆DEF

Also, BC = 9.1 cm & EF = 6.5 cm

And perimeter of ∆DEF = 25 cm

We need to find perimeter of ∆ABC = ?

We can write relationship as,

⇒

⇒ perimeter of ∆ABC = 35

Thus, perimeter of ∆ABC = 35 cm
