The area of the rectangle is 72cm2, its width is 6cm. Find the perimeter of this rectangle.

1. The area of a rectangle is equal to the product of its length by its width. Therefore, to find the length of a rectangle, it is necessary to divide its area by its width. Let’s find the length of the rectangle if it is known that its area is 72 cm ^ 2, and its length is 6 cm.

72/6 = 12 cm.

2. The perimeter of a rectangle is the sum of the lengths of all its sides. A rectangle has 2 sides equal to its length and 2 sides equal to its width. Let’s calculate the perimeter of the given rectangle.

6 * 2 + 12 * 2 = 12 + 24 = 36 cm.

Answer: The perimeter of the rectangle is 36 cm.
