If ∆ABC ∼ ∆QRP, AB = 18 cm and BC = 15 cm, then PR is equals to,

Question

Philoid · Accepted Answer

Given,

∆ABC ∼ ∆QRP

AB = 18 cm and

BC = 15 cm

By Similar triangles area property, the ratio of area of two similar triangles is equal to the ratio of square of their corresponding sides.

So,

We have,

(By similar triangles area property).

But given

∴ RP = √100 = 10 cm
