Question

find the length of two sides of an equilateral triangle having area under root 3 cm cube​

Answer 1

Let each side of equilateral triangle = a

Area = 9√3 cm sq.

Area of equilateral triangle = √3 / 4 × side sq.

9√3 = √3 /4 × a

9 × 4 = √3 / √3 × a

36 = 1 × a

Therefore, length of each side = a = 36cm
