Find the area of the given trapezoid.
Bases: 13 cm and 16 cm; Height: 12 cm
user
the formula for the area of a trapezoid is $a=\frac{1}{2}(b_1+b_2)h$, where $b_1$ and $b_2$ are the lengths of the bases and $h$ is the height. in this case, we have $b_1=13$ cm, $b_2=16$ cm, and $h=12$ cm. substituting these values into the formula, we get $a=\frac{1}{2}(13+16)(12)=\boxed{204\text{ cm}^2}$.
