Question

In triangle abc and triangle pqr are similar triangles such that a triangle ABC area is 49 CM square and area of triangle pqr is equal to 25 CM square if a b is equals to 5.6 cm find the length of PQ

Answer 1

Given that ABC is similar triangle to PQR.

Hence, the ratio of corresponding sides= the ratio of square root of the area of ABC and PQR.

The ratio of corresponding sides= square root of 49/25=7/5

Now,

AB/PQ=7/5

PQ=AB*5/7

PQ=5.6*5/7=3.9999

Therefore, the length of PQ is 4 (approx)
