If triangle ABC congruent to triangle PQR , BC = 8 cm and QR = 6 cm, find the ratio of the areas of triangle ABC and PQR.

Dear student
The correct question is:

If ABC is similar to PQR,BC=8 cm and QR=6 cm, find the ratio ofareas of ABC and  PQR.Solution:We know that the ratio of the areas of two similar trianglesis equal to the ratio of the squares of any two  corresponding sides.So, ABCPQR=BC2QR2=8262=6436=169
