Answer 1

$\huge \underbrace \mathfrak \red{Answer࿐꧂}$

Step-by-step explanation:

Let each side of an equilateral be x.

Then, perimeter of an equilateral triangle = 60 m

x + x + x = 60

⇒ 3x = 60

⇒ x = 60/3 = 20 m

Area of an equilateral triangle = √3/4 (Side)2 = (√3/4) x 20 x 20 = 100 √3 m2

Thus, the area of triangle is 100√3 m2.

Answer 2

Step-by-step explanation:

Perimeter of triangle = 3a = 60

a = 60 / 3

= 20m

Area of a traingle = √3a² / 4

= √3(400) / 4

= 100√3m²
