Rose's garden is in the shape of a trapezoid. If the height of the trapezoid is 16m, one base is 20m, and the area is 224 m squared, find the length of the other base.

The height dimension h is measure perpendicular to the to parallel "base" sides, a and b.
The area is h*(a+b)/2 = 224
You know a and h, so solve for b.
