Explanation:

Step1: Find area of outer rectangle

$\text{Area}_{\text{outer}} = 9 \times 8 = 72$ $\text{in}^2$

Step2: Find area of inner empty rectangle

$\text{Area}_{\text{inner}} = 6 \times 5 = 30$ $\text{in}^2$

Step3: Subtract inner from outer area

$\text{Area}_{\text{colored}} = 72 - 30$

Answer:

$42$ $\text{in}^2$
