Question

Area of an equilateral triangle is 100 root m 3 find perimeter

Answer 1

Hi ,

Let the side of a equilateral

triangle = a m

i ) Area = 100√3 m²

( √3/4 )a² = 100√3

a² = ( 100√3 × 4 )/√3

a² = 400

a = √400

a = √ 20²

a = 20 m

ii ) Perimeter of the equilateral

triangle = 3a

= 3 × 20m

= 60m

I hope this helps you.
