Question: 1 / 400

What's the perimeter of a rectangle with length 7 feet and width 3 feet?

20 feet

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

Perimeter = 2 × (Length + Width)

In this case, the length of the rectangle is 7 feet, and the width is 3 feet. Plugging these values into the formula gives:

Perimeter = 2 × (7 feet + 3 feet)

Perimeter = 2 × (10 feet)

Perimeter = 20 feet

Thus, the calculated perimeter of the rectangle is 20 feet. This matches one of the options and confirms that it's the correct choice.

Understanding that the perimeter is simply the total distance around the rectangle helps in applying the formula effectively. The addition of length and width, followed by multiplication, is critical in arriving at the correct perimeter.
