Perimeter and Area of a Rectangle

To find the perimeter and area of a rectangle, we need to know its length and width. In this case, the length of the rectangle is 9 cm and the width is 5 cm.

Perimeter is the distance around the outside of a shape. For a rectangle, the perimeter is calculated by adding up all the sides. In this case, the formula for the perimeter of a rectangle is:

P = 2 * (length + width)

Substituting the given values, we have:

P = 2 * (9 + 5) = 2 * 14 = 28 cm.

Therefore, the perimeter of the rectangle is 28 cm.

Area is the measure of the space inside a shape. For a rectangle, the area is calculated by multiplying the length and width. In this case, the formula for the area of a rectangle is:

A = length * width

Substituting the given values, we have:

A = 9 * 5 = 45 cm².

Therefore, the area of the rectangle is 45 cm².

So, the perimeter of the rectangle is 28 cm and the area of the rectangle is 45 cm².
