The area of a trapezoid is 70.55 square feet. The length of the bases are 11.4 feet and 5.6 feet. What is the height of the trapezoid?

8.3 feet.

Step-by-step explanation:

Area = (h/2)(a + b)   where h = height and a and b are the lengths of the 2 bases.

70.55 = (h/2)(11.4 + 5.6)

(h/2)(17) = 70.55

h/2 = 70.55/17

h = (2 * 70.55) / 17

h = 8.3 feet.

4.6875 pounds
