Question

If the area of an equilateral triangle is 36 root 3 find its perimeter

Answer 1

36 cm is the right answer

Answer 2

area of equilateral triangle = 36√3

√3/4 a² = 36√3   (here a is refers to the side of the equilateral triangle)

a² = 36√3 × 4/√3

a² = 36 × 4

a² = 144

a  = √144

a = 12 units



perimeter of equilateral triangle

= 3a

= 3(12)

= 36 units

so the perimeter of the equilateral triangle is 36 units
