(b) The length of each side of a square is 6 cm. Find the side of an equilateral triangle

9. The length and breadth of a rectangle are 12 cm and 9 cm respectively.​

Answer 1

Answer:

Perimeter of a square = 4 × side

= 4 × 6 cm = 24cm

A.T.Q.

Perimeter of the square = Perimeter of the triangle

4 × Side = 3 × Side { let the side be 's' }

24 = 3s

24 ÷ 3 = s

8 = s

= Hence, side of that equilateral triangle is 8cm.
