find the area of a regular hexagon with an apothem 13 inches long and a side 15 inches long. round your answer to the nearest tenth.
585 in2
389.7 in2
97.4 in2
1,169.1 in2

An apothem is a line drawn from the centerpoint of the polygon to one side of the polygon. There is a formula for area in terms of apothem:

A = (1/2)*(Perimeter)*(Apothem)

The perimeter of the regular hexagon is just the length of one side multiplied with the number of sides. Since a hexagon has 6 sides,

P = 6(15) = 90in

A = 1/2 * 90 * 13
A = 585 square inches
