 $\begin{array}{r} b_{1} = & 6 \\ b_{2} = & 7 \\ h = & 5 \end{array}$

Step 1

The area of a trapezoid is equal to $\frac{1}{2}$ times the height times the sum of the bases $b_{1} + b_{2}$ .

$\frac{1}{2} \cdot (h e i g h t) \cdot (b_{1} + b_{2})$

Step 2

Substitute the values of the height $h = 5$ and bases ( $b_{1} = 6$ and $b_{2} = 7$ ) into the formula for the area of a trapezoid.

$\frac{1}{2} \cdot 5 \cdot (6 + 7)$

Step 3

Combine $\frac{1}{2}$ and $5$ .

$\frac{5}{2} \cdot (6 + 7)$

Step 4

Add $6$ and $7$ .

$\frac{5}{2} \cdot 13$

Step 5

Multiply $\frac{5}{2} \cdot 13$ .
