Answer: 21 units²

Explanation:

Since there is a pair of parallel sides, this figures is a trapezoid. The formula for the area of a trapezoid is
(1)/(2)(a+b)h, where a and b are the parallel sides and h is the height.

Here, a and b are 5 and 9, while 3 is the height. Let's put all 3 values into the formula.


A=(1)/(2)(5+9)*3


A=(1)/(2)(14)*3 [Adding in the parentheses]


A=7*3 [Multiplying one-half by 14]


A=21 [Multiplying 7 and 3]

The area is 21 units².
