First, find the length of one of the diagonal sides using the Pythagorean Theorem. Since the base is 54, the distance from the center point to the edge, which is the 'a' side of the triangle, would be 27.

a² + b² = c²

27² + 31² = c²

729 + 961 = c²
1690 = c²
41.11 = c



Now, multiply the height of the diagonal by the perimeter and divide by two.

(216 * 41.11)/2 = 4439.8







ANSWER

4440 yds²
