Question

The perimeter of equilateral triangle shaped garden is 48m. Find its area

Answer 1

let the side of equilateral triangle =a
then the perimeter= 3a=48
a=16
now area of equilateral triangle =root3×a^2/4
root3×(16)^2/4
64×root3
=110.72 m sq.

I hope it will help you ☺

Answer 2

As we know that,

Perimeter of equilateral triangle =3*side

Here,

48=3*side

48/3 =side

16=side

Now,

Area of equilateral triangle =side²√3/4

Then,

Area of given triangle =16²√3/4

Area of triangle =16*4√3.

Area of triangle =64√3 m²
