Question

A wire is bent in the form of an equilateral triangle of each side 20 cm. If the same wire is bent in the form of a square, find the side of the square.

Answer 1

∵ Each side of the given equilateral triangle = 20 cm

∴ Perimeter of the triangle = 3 x side = 3 x 20 cm = 60 cm,

∴ Perimeter of the square = Perimeter of equilateral triangle

⇒ 4 x side of square = 60 cm

⇒ The side of the square = `60/4`

= 15 cm
