A trapezoid has an area of 59.2 square kilometers. One base is 9.8 kilometers long. The height measures 8 kilometers. What is the length of the other base?

The formula for the area of a trapezoid is:$${{h(a+b)}\over2}$$

In the equation, h is the height, a is base 1, and b is base 2.

$${{8(9.8+x)}\over2}=59.2$$

$$4(9.8+x)=59.2$$

$$14.8=9.8+x$$

Thus, the base of the other side is $$\color{brown}\boxed{5}$$
