The width of the rectangle (4 cm) and its length (5 cm) are known. Find the perimeter of the shape. Recall that the rectangle has 2 opposite sides. And the perimeter is the sum of all the sides of the figure.
P = 4 cm + 4 cm + 5 cm + 5 cm or P = 4 * 2 + 5 * 2.
P = 18 cm.
Let’s find the area.
The area of a rectangle is its width times its length.
S = a * b.
S = 4 * 5.
S = 20 square centimeters.
The perimeter is measured in cm and the area is measured in square cm.
The perimeter is the sum of all sides, and the area is the product of a and b.
