Q8 of 95 Page 6

The perimeters of two similar triangles, ABC and PQR (ΔABC~ ΔPQR) are respectively 72 cm and 48 cm. If PQ = 20 cm, find AB.

Given: ABC~PQR, PQ =20cm

And perimeter of ABC andPQR are 72cm and 48cm respectively.


As, ABC ~PQR


(corresponding sides are proportional)







⇒AB = 30cm
