So we can deduce that the figure is a **trapezoid**, which **means** the **trapezoid** area
formula is in play. The bases of the **trapezoid** are the parallel sides, and we're
told their lengths are 6 and 10. So far so good, but to find the area, we also need
to find the **trapezoid's** height, which isn't given. To **do** that, split the **trapezoid** into
a ...
