Question

The perimeter of an equilateral tolongle is 60m. The area is
loo√3 m². prove it.​

Answer 1

Step-by-step explanation:

perimeter of  equilateral triangle = 60 m =3 a

=> side of triangle = 60 / 3 = 20 m = a

area of equilateral triangle = √3/4 a² = √3/ 4 x (20)²

                                                             =  √3/4 x 400

                                                              = √3 x 100 m²

Hence proved.
