Question

if the area of a equilateral triangle is 78root3 then find the perimeter of the triangle​

Answer 1

Step-by-step explanation:

We know that,

Area of an equilateral triangle = (√3/4)*side²

Let, the sides of the equilateral triangle is a

So,

4√3 = (√3/4)*a²

=> 4*4 = a²

=> 16 = a²

=> a = 4

So , Side of the equilateral triangle is 4 units.

Therefore, Perimeter of the equilateral triangle = 3* side

= 3*4 units

= 12 units.

So,

Required Perimeter is 12 units.
