If a rectangle has a length of 8 and a width of 5, what is its perimeter?

To find the perimeter of a rectangle, you can use the formula: Perimeter = 2 × (Length + Width). In this case, the length of the rectangle is 8 and the width is 5.

First, add the length and the width together:

8 + 5 = 13.

Next, multiply the sum by 2 to find the perimeter:

2 × 13 = 26.

Thus, the perimeter of the rectangle is 26. This calculation correctly utilizes the formula for perimeter based on the dimensions provided.
