Can I say this: A = 1/2 * x * y x = 10.4 12 * 6 = 72 y = 72 10.4 * 72 = 748.8 748.8 / 2 = 374.4 A = 374.4 yards^2

area?

Well, we already were given the apothem to be 10.4 yards. The perimeter is the distance around our hexagon. But since we have the side length, and all the sides of a regular hexagon are the same, we can multiply the side length 12 by the number of sides 6 for the total perimeter. Is that clear?

OpenStudy (anonymous):

Have you encountered this formula before? A=\[\frac{ ap }{ 2 }\] Where p is the perimeter and a is the apothem.

Okay soo... A = 1/2 * a * p a = 10.4 12 * 6 = 72 p = 72 10.4 * 72 = 748.8 748.8 / 2 = 374.4 A = 374.4 yards^2
