Answer:

As we know that in equilateral triangle all side are same

so let side be a

than perimeter of a triangle is sum of all side

a+a+a=60

3a=60

a=60/3

a=20m side is 20m

formula of area of equilateral triangle is ✓3asquare/4

√3×(20)square/4=100√3m2

otherwise do with heron formula

Perimeter of Equilateral triangle =60 m

One side = $\Large{\frac{60}{3}}$

⚡Side = 20 m⚡

Area of Equilateral triangle = $\large{\frac{\sqrt{3}}{4}a^2}$

⭐Where a is the Side.....

➡️ $\frac{\sqrt{3}}{4}×20^2$

➡️ $\frac{\sqrt{3}}{4}×400$

➡️ $\sqrt{3}×100$

➡️ $1.732×100$ ___{Using $\sqrt{3}=1.732$ }
