Answer: The area of the trapezoid can be found using the formula:
Area = (a + b)h/2
where a and b are the lengths of the parallel sides and h is the height (perpendicular distance between the parallel sides).
In this case, the parallel sides are 13ft and 15ft, and the height is 5ft.
Therefore, the area of the trapezoid is:
(13 + 15) * 5 / 2 = (28) * 5 / 2 = 140 / 2 = 70 ft^2
Step-by-step explanation: The area of the trapezoid is calculated by taking the sum of the parallel sides, multiplying by the height and then dividing by 2. The parallel sides are given as 13ft and 15ft, and the height is given as 5ft.
By substituting the given values in the formula we get (13+15)5/2 = 285/2 = 140/2 = 70 ft^2.
So, the area of the trapezoid is 70 ft^2.
