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

olasank [31]

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.

$70.55 = \frac{1}{2} (11.4 + 5.6)h$

$70.55 = \frac{1}{2} (17)h$

$70 .55 = 8.5h$

$h = \frac{70.55}{8.5}$

$h = 8.3$
