Correct Answer: D
Explanation:
To find the perimeter of a rectangle, we will use the following formula:
P = 2l + 2w
Where l is the length and w is the width of the rectangle.
Now, we know the width of the rectangle is 8in. We also know the length is two times the width. Therefore, the length is 16in. So, we can substitute. We get
P = 2(16in) + 2(8in)
P = 32in + 16in
P = 48in
