Question

A (∆ ABC ) = 9 cm square , A(∆ PQR) = 64 cm . If∆ ABC ~∆ PQR than AB : PQ ​

Answer 1

Answer:

3/8

is the correct answer

Answer 2

Answer:

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

∴ar(ΔPQR)ar(ΔABC)=QR2BC2⇒12164=(15.4)2BC2

⇒118=15.4BC

⇒BC=118×15.4=11.2cm
