Answer 2

Hey there,

Here's the answer to your question:

We know that,

The ratio of the perimeters of two similar triangles is equal to the ratio of their corresponding sides.

(Fun fact: This ratio is also called as scale factor of the triangles.)

Now, ΔABC ~ ΔPQR

This means,

(Per)ΔABC/(Per)ΔPQR = 35/49 = AB/PQ = 5/7 [By theorem]

But we also know that,

The ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides.

Therefore,

(Ar)ΔABC/(Ar)ΔPQR = (AB/PQ)^2

But AB/PQ = 5/7 [Proved Above]

Therefore,

(Ar)ΔABC/(Ar)ΔPQR = (5/7)^2 = 25/49.

Hope it helps, please mark me as brainliest, as it would be much appreciated :))

Have a great day! ;)
