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

To determine the perimeter of a rectangle, the formula used is:

Perimeter = 2 × (Length + Width)

In this case, the rectangle has a length of 8 units and a width of 3 units. Plugging these values into the formula gives:

Perimeter = 2 × (8 + 3)

Perimeter = 2 × 11

Perimeter = 22 units

This calculation shows that the perimeter of the rectangle is indeed 22 units, which corresponds to the first choice. The correct answer accurately reflects the mathematical operation needed to find the perimeter based on the given dimensions of the rectangle.
