Areas of two simi

Given,

Area of smaller triangle = 36 cm²

Area of larger triangle = 100 cm²

Also, length of a side of the larger triangle = 20 cm

Let length of the corresponding side of the smaller triangle = x cm

By property of area of similar triangle.

∴ x = √144 = 12 cm

Hence, the length of corresponding side of the smaller triangle is 12 cm.
