Question

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

Answer 1

Answer:

24.2 cm²

Step-by-step explanation:

Answer 2

Answer: 24.25$cm^{2}$

Step-by-step explanation:

The formula for calculating the area of a triangle given the apothem and perimeter is

Area = $\frac{1}{2}$ x apothem x perimeter

apothem = 2.16

perimeter = 22.45

substituting into the formula , we have

Area = $\frac{1}{2}$ x 2.16 x 22.45

Area = 24.246$cm^{2}$

Area≈ 24.25$cm^{2}$
