Question

If the perimeter of an eqilateral triangle is 60cm wht is iths area? how do you find that?

Answer 1

P=60
since all the sides are equal of an equilateral triangle
therefore,3x=60
x=20
area of equilateral triangle=√3/4×(side)^2
=√3/4×20×20
=100√3

Answer 2

perimeter of a equilateral traingle =3*side or sum of all sides.
