Question

What is the area of the shape?

Answer 1

Answer: 21 units²

Step-by-step explanation:

Since there is a pair of parallel sides, this figures is a trapezoid. The formula for the area of a trapezoid is $\frac{1}{2}(a+b)h$, 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.

$A=\frac{1}{2}(5+9)*3$

$A=\frac{1}{2}(14)*3$ [Adding in the parentheses]

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

$A=21$ [Multiplying 7 and 3]

The area is 21 units².
