Question

What is the side length of an equilateral triangle whose area is 15√3cm square

Answer 1

Let each side of equilateral triangle = a

Area = 15√3 cm sq.

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

15√3 = √3 /4 × a

15× 4 = √3 / √3 × a

60 = 1 × a

Therefore, length of each side

a = 60cm.
