The answer is C- 407.0652
Round each number to the nearest 10.
33 rounds to 30 and 89 rounds to 90, thus in your head it's easier to mentally add 30 + 90 for purposes of estimation.
The hexagon is made up of 6 triangles. So we need to multiply the area of the triangle by 6 to find the answer.
Area of triangle = b x h / 2
A = 14 x 12.1 / 2
A = 169.4 /2
A = 84.7 ft squared
Area of hexagon = 84.7 x 6
= 508.2 ft squared
