What is the perimeter of a rectangle that is 5 units long and 3 units wide?

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

Perimeter = 2 × (length + width).

In this case, the rectangle has a length of 5 units and a width of 3 units.

First, add the length and the width together:

5 + 3 = 8 units.

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

2 × 8 = 16 units.

Thus, the perimeter of the rectangle is 16 units, which corresponds to the correct answer. Understanding the perimeter as the total distance around the rectangle helps reinforce this concept, showing how the dimensions contribute to the overall measurement.
