Calculation of Area and Perimeter

To find the area and perimeter of a rectangle with a length of 4 cm and a width that is twice the length, we can follow these steps:

1. Calculate the width: - The width is twice the length, so the width is 4 cm * 2 = 8 cm.

2. Calculate the area: - The area of a rectangle is given by the formula: Area = length * width. - Substituting the values, we have: Area = 4 cm * 8 cm = 32 cm². 3. Calculate the perimeter: - The perimeter of a rectangle is given by the formula: Perimeter = 2 * (length + width). - Substituting the values, we have: Perimeter = 2 * (4 cm + 8 cm) = 2 * 12 cm = 24 cm. Therefore, the area of the rectangle is 32 cm² and the perimeter is 24 cm.
