Question

PLEAEE NEED HELP!!

Find the area of the shaded region in the regular polygon with AB = 5.5 ft.

Answer 1

88 ft^2

Explanation:

please find attached the diagram used in answering this question

Area of shaded region = area of regular polygon - area of triangle

area of regular polygon = 1/2 x height x perimeter of the polygon

perimeter of the polygon = number of sides x length of side

5 x 8 = 40

1/2 x 40 x 5.5 = 110 ft²

Area of a triangle = 1/2 x ( base x height)

1/2 x 5.5 x 8 = 22 ft²

Shaded portion = 110 - 22 = 88 ft²
