उत्तर
The perimeters of two similar triangles ABC and PQR are 56 cm and 48 cm respectively. PQ/AB is equal to `bbunderline(6/7)`.
Explanation:
The ratio of the corresponding sides of similar triangles is same as the ratio of their perimeter.
∴ ΔABC ~ ΔPQR or ΔPQR ~ ΔABC
⇒ `(PQ)/(AB) = (QR)/(BC) = (PR)/(AC) = 48/56`
⇒ `(PQ)/(AB) = 6/7`
