If area of an equilateral triangle is 9?3 cm^2 find its length of each side. Also find its perimeter

Open in App

Solution

Dear student

Given, area of an equilateral triangle = 9√3 cm²
∴ Area of an equilateral triangle = √3/4(Side)²
⇒ √3/4 (Side)2 = 9√3
⇒ (Side)2 = 36
∴ Side = 6 cm

perameter is 3side=36=18

Regards
