Answer:
The height is 8.3 feet
Step-by-step explanation:
The area of a trapezoid is calculated using the formula:
Area=½(sum of bases)*height
We substitute area=70.55, and the base lengths 11.4 and 5.6 feet and solve for the height.
[tex]70.55 = \frac{1}{2} (11.4 + 5.6)h[/tex]
[tex]70.55 = \frac{1}{2} (17)h[/tex]
[tex]70 .55 = 8.5h[/tex]
[tex]h = \frac{70.55}{8.5} [/tex]
[tex]h = 8.3[/tex]
