Calculation of the Area and Perimeter of a Rectangle

To find the area and perimeter of a rectangle, we need to know the length and width of the rectangle. In this case, the length is 18 cm and the width is 5 cm.

Area of a Rectangle: The area of a rectangle is calculated by multiplying the length by the width. So, the area (A) of this rectangle is given by the formula A = length * width.

Using the given values, the area (A) of the rectangle is: A = 18 cm * 5 cm = 90 cm^2.

Perimeter of a Rectangle: The perimeter of a rectangle is calculated by adding the lengths of all four sides. In the case of a rectangle, opposite sides are equal in length. So, the perimeter (P) of this rectangle is given by the formula P = 2 * (length + width).

Using the given values, the perimeter (P) of the rectangle is: P = 2 * (18 cm + 5 cm) = 2 * 23 cm = 46 cm.

Therefore, the area of the rectangle is 90 square centimeters, and the perimeter is 46 centimeters.
