A trapezoid’s area can be calculated by the formula $A=\frac{1}{2}(b_1+b_2)h$, where $A$ stands for area, $b_1$ for the first base’s length, $b_2$ for the second base’s length, and $h$ for height. Use the formulas to calculate the trapezoid’s area if its first base’s length is ${14\ {\rm m}}$, its second base’s length is ${9\ {\rm m}}$ and its height is ${8\ {\rm m}}$. (Use m for meters and m^2 for square meters.)
