If the base lengths of a trapezoid are 11 cm and 17 cm, then what is the length of the trapezoid's midsegment?

Accepted Solution

The answer is 14 centimeters.
The midsegment of a trapezoid has length equal to the average of the two base lengths. Since the base lengths of this trapezoid are 11 and 17 centimeters, our midsegment has length (11+17)/2 = 14 centimeters.
