To determine

a)

To find:

The area of the equiangular triangle.

Explanation

1) The perimeter of the equiangular is given by, P = 3s where s is side of the equiangular.

2) The area of the equiangular triangle is given by, A=34s2 where s is side of the equiangular triangle.

Calculation:

It is given that the perimeter of the equiangular is 24.6 cm.

Use the formula of perimeter of the equiangular, P = 3s

Substitute P = 24.6 in P = 3s.

24.6=3ss=24.63=8
