Question

An equilateral triangle has an apothem measuring 2.16 cm and a perimeter of 22.45 cm.

An equilateral triangle has an apothem with length 2.16 centimeters and a perimeter of 22.45 centimeters.

What is the area of the equilateral triangle, rounded to the nearest tenth?

2.7 cm2
4.1 cm2
16.2 cm2
24.2 cm2

Answer 1

The area is 24.2 cm^2

Explanation:

Here, we want to find the area of an equilateral triangle, given its apothem and perimeter

Mathematically;

Area = (perimeter * apothem)/2

Area = (22.45 * 2.16)/2 = 24.246 cm^2 which you the nearest tenth is 24.2 cm^2
