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 \(\color{brown}\boxed{5}\)
