What is the perimeter of a rectangle with a length of 8 units and a width of 3 units?

To find the perimeter of a rectangle, you use the formula:

Perimeter = 2 × (length + width)

In this case, the length is given as 8 units and the width is 3 units. Plugging these values into the formula gives:

Perimeter = 2 × (8 + 3)
= 2 × 11
= 22 units

This calculation shows that the perimeter of the rectangle is indeed 22 units. It's essential to remember that using the sum of the length and width and then multiplying by 2 helps you account for both pairs of opposite sides of the rectangle, resulting in the correct total perimeter.

Therefore, the answer is accurately determined as being 22 units.
