What is the perimeter of a rectangle whose width is 4cm and it is 3 times less than its length?

By the condition of the problem, it is known that the width of the rectangle is 4 centimeters, and that the width is 3 times less than its length.

It is required to calculate what the perimeter of this rectangle is.

Since the width of the rectangle is 3 times less than its length, therefore the length is 3 times the width.

Let’s find the length of the rectangle.

4 * 3 = 12 cm.

The perimeter of a rectangle is twice the sum of its length and width.

Let’s find the perimeter.

P = 2 * (4 + 12) = 2 * 16 = 32 cm.

Answer: The perimeter of the rectangle is 32 centimeters.
