Question

Areas of two similar triangles are 225 sq. cm. and 81 sq. cm. If a side of the smaller triangle is 12 cm, then find corresponding side of the bigger triangle.

Answer 1

Let the areas of two similar triangles be A₁ and A₂ .

A₁ = 225 sq. cm. A₂ = 81 sq. cm. 

Let the corresponding sides of triangles be S₁ and S₂ respectively. 

S₁ = 12 cm

∴ The length of the corresponding side of the bigger triangle is 20 cm.
