Question

find the area of the figure. (sides meet at right angles.)

Explanation:

Step1: Calculate area of outer rectangle

$\text{Area}_{\text{outer}} = 13 \times 6 = 78$ $\text{in}^2$

Step2: Calculate area of inner cutout

$\text{Area}_{\text{cutout}} = 5 \times 4 = 20$ $\text{in}^2$

Step3: Subtract cutout from outer area

$\text{Area}_{\text{total}} = 78 - 20$

Answer:

$58$ $\text{in}^2$
