Question

The area of an equalilateral triangle is 36√3 sq.cm .Find the perimeter? "Give me the way to solve it"

Answer 1

perimeter of equilateral triangle is 36cm

Answer 2

let sides are = a
height h = √3/2 a
area of triangle = 1/2 ×a×h
= 1/2 × a ×√3/2×a = 36√3
a = 12

now periphery is = a+a+a
= 12+12+12
= 36 cm
