A lot is in the shape of a trapezoid. The sum of the bases is 180 feet. If the area of the lot is 8,100 square feet, what is the distance across the lot, i.e., the altitude of the figure?

Question

The altitude of the trapezoid is how many feet?

Answer 1

A = ((B1 + B2)/2)h = 8100F^2.

(180 / 2)h = 8100,
90h = 8100,

h = 8100 / 90 = 90Ft = Distance across
the lot.
