Practice makes perfect
The area of a trapezoid is one half the product of its base and the sum of its bases.
In the given diagram, we can see that the lengths of the bases are 12 in. and 18 in., and the height is 9 inches. Having the height and the lengths of the bases, we can substitute them into the formula.
