Answer 2

Anwer :

100√3

                               

Step-by-step explanation:

Perimeter = 60 m

One side (a) = 60/3 = 20 m

Area of Triangle = √3/4 a²

                           = √3/4 × 20²

                           = √3/4 × 400

                           = √3 × 100

                           = 1.73 × 100

                           = 173 m²

∴ Area of Triangle = 173 m²
