Question

a rectangular region is removed from another rectangular region to create the shaded region shown below. find the area of the shaded region.
(there is a diagram showing a larger rectangle with length 11 ft and height 7 ft, and a smaller rectangle inside with length 4 ft and height 2 ft)

Explanation:

Step1: Calculate area of large rectangle

$\text{Area} = 11 \times 7 = 77$ $\text{ft}^2$

Step2: Calculate area of small rectangle

$\text{Area} = 4 \times 2 = 8$ $\text{ft}^2$

Step3: Subtract small area from large area

$\text{Shaded Area} = 77 - 8 = 69$ $\text{ft}^2$

Answer:

69 $\text{ft}^2$
