Question

Corresponding sides of two similar triangles are in the ratio of 2:3. If the area of small triangle is 48
sq.cm, then the area of large triangle is:

Answer 1

Answer:

108 sq. cm

Explanation:

Ratio of Area of similar triangles is equal to the square of he proportional sides.

$ar(∆ABC)/ ar(∆PQR) = {AB}^{2} /{PQ}^{2}$

ar(∆ABC)/ ar(∆PQR) = 4:9

48:x = 4:9

x = 108 sq. cm
