Question

Use the perimeter formula to find the perimeter of the rectangle.

a vertical rectangle with one side length labeled 11 inches and another side length labeled 9 inches

40 inches
31 inches
22 inches
18 inches

Answer 1

Perimeter = 40 inches

Explanation:

The formula for the perimeter of a rectangle is given by:

P = 2l + 2w, where,

• P is the perimeter,
• l is the length,
• and w is the width.

Thus, we can allow the 11-inch side to represent the length and the 9-inch side to represent the width and plug in 11 for l and 9 for w in the perimeter formula to find P, the perimeter of the rectangle:

P = 2(11) + 2(9)

P = 22 + 18

P = 40

Thus, the perimeter of the rectangle is 40 inches.
