Question

GEOMETRY- FIND POLYGON AREA

Answer 1

Explanation:

The area of a regular polygon is

`A=(1)/(2)ap` where a is the apothem and p is the perimeter. Perimeter is simple: just count the number of sides the polygon has and multiply it by 3 (the length of one side).

p = 3(9) is 27 inches for the perimeter.

We have what we need now to find the area:

`A=(1)/(2)(4.1)(27)` and

`A=(1)/(2)( 110.7)` so

A = 55.35 square inches
