Perimeter of the square = Perimeter of an equilateral triangle with side 20 cm

4a = 3 x 20

60

4

a=

48

... a = 15 cm

i.e., Side of the square = 15 cm

Answer 2

Answer:

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
