Question

If the area of equilateral triangle is 36√3cmsq. ,Find its perimeter please give solution

Answer 1

Heya !!



Area of an equilateral triangle = 36✓3




✓3/4 × ( Side)² = 36✓3




(Side)² = ( 36✓3 × 4 ) / ✓3




(Side)² = 144



side = ✓144 = 12 cm



Therefore,


Perimeter of an equilateral triangle = 3 × Side


=> 3 × 12



=> 36 cm.

Answer 2

Hey!!

Area of an equilateral triangle = 36√3 cm^2

=> √3 / 4 × ( side )^2 = 36√3 cm^2

=> ( Side )^2 = ( 36√3 × 4 ) / √3

=> ( Side )^2 = 144 cm

=> Side = √144 cm^2

=> Side = 12 cm

Perimeter of an equilateral triangle = 3 × side

=> 3 × 12 cm

=> 36 cm >>>>> Answer
