Find the area of an equilateral triangle with apothem a = 4.6 in. and perimeter P = 27.6 3 in.

To determine

To find:

The area of an equiangular triangle.

Explanation

The area of an equiangular triangle with apothem a and perimeter P is given by A=12(aP).

Calculation:

It is given that the apothem and perimeter of the equiangular triangle are 4.6 and 27.63 in respectively.

Use the formula of area of equiangular triangle, A=12(aP)

Substitute a = 4.6 and P = 27.63 in A=12(aP).

A=12(4
