A section in a stained glass window is shaped like a trapezoid. The top base is 4 centimeters and the bottom base is 2.5 centimeters long. If the area of the section of glass is 3.9 square centimeters, how tall is the section?
The area of a trapezoid can be found with the formula [tex]A=\frac{b_1+b_2}2h[/tex] where b1 and b2 are the bases and h is the height. Let's plug in the values that we know and solve for h.
