Explanation:
The figure shows a regular pentagon with the radius and the length of one side given. The Pythagorean theorem to find the missing side of the right triangle whose given sides are the pentagon radius and half the side length. That missing side is the apothem of the pentagon. As with any regular polygon, the area of this pentagon will be half the product of the perimeter and the apothem. The perimeter of a pentagon is 5 times the side length. All dimensions are in feet, so the area will be in square feet.

<em>Additional comment</em>
The working out was not requested, but here it is, anyway.
a = √(40.8² -(48/2)²) = √1088.64 ≈ 32.99 . . . feet
P = 5(48 ft) = 240 ft
A = (1/2)Pa = (1/2)(240 ft)(32.99 ft) = 3959.3 ft²
Note that the radius has been rounded down to the nearest tenth. If the full-accuracy value were used, the area would be found to be 3963.98 ft².
