Question

The area of an equilateral triangle is 100V3 m2. Find the perimeter of the triangle.​

Answer 1

Area of an equilateral triangle = 100√3 m²

we know area of an eq triangle = √3/4 × ( a)²

{where a is the side of the triangle }

(√3 / 4) a² = 100 √3

a² / 4 = 100

a² = 400

a = √400

a = 20 m

Perimeter of triangle = 3a = 3 × 20 = 60 cm

Hope the solution is clear to you!!
