Question

a rectangular region is removed from another rectangular region to create the shaded regions shown below. find the combined area of the shaded regions.
7 ft
2 ft
15 ft
ft²

Explanation:

Step1: Calculate area of large rectangle

$\text{Area}_{\text{large}} = 15 \times 7 = 105 \ \text{ft}^2$

Step2: Calculate area of removed rectangle

$\text{Area}_{\text{removed}} = 7 \times 2 = 14 \ \text{ft}^2$

Step3: Subtract to get shaded area

$\text{Area}_{\text{shaded}} = 105 - 14 = 91 \ \text{ft}^2$

Answer:

$91$
