Question

If its perimeter of an equilateral triangle is 180 cm, what will be its area​

Answer 1

Answer:

Perimeter of △ABC= 180cm. So the side of an equilateral triangle is 60cm. Area of the equilateral triangle is given as Area = √34x2 where x is the side of the equilateral triangle. Hence the area of the triangle is 1558.84cm2.

Answer 2

Answer:

1800 cm²

Step-by-step explanation:

perimeter of equilateral triangle= side + side + side

Let the side of triangle be X

X+X+X = 180 cm

3x = 180 cm

so, X= 180÷ 3 = 60 cm

area of triangle = ½ × base × height

= ½ × 60×60

= 1800 cm²
