Answer:
Step-by-step explanation:
Remark
Don't be fooled by that top base. The lines (b2 and b1) are parallel. Not only that the height and the left side of the trapezoid form a rectangle.
That being so the top base B1 is 13 feet
Givens
B1 = 13 feet
B2 = 13 + 5 = 18 feet
h = 14 feet
Formula
Area = (B1 + B2)*h/2
Area = (13 + 18)*14/2
Area = 31 * 7
area = 217 square feet.
