Question

The perimeter of an equilateral triangle is numerically equal to its area.find the length of the side of the equilateral triangle.​

Answer 1

Answer:

6

Step-by-step explanation:

perimeter of etquilateral triangle = 3a

area = 1/2 a^2

3a = 1/2 a^2

6a = a^2

a = 6

Answer 2

Answer:

Let length of each side of the equilateral triangle=a cm

A.T.Q,

3a=(√3 × a²)/4

=>12a=√3a²

=>12/√3=a²/a

=>4√3=a

∴Length of its side=4√3 cm
