The area of a rectangle is 560 square centimeters. Find the sum of the lengths of its sides

The area of a rectangle is 560 square centimeters. Find the sum of the lengths of its sides if the length of the rectangle is 80cm.

To solve this problem, recall the formula for the area of a rectangle. The area of the rectangle is equal to the product of the length and the width. S = a * b, where a is the length and b is the width. The perimeter of a rectangle is the sum of the lengths of all its sides. Since in a rectangle the opposite sides are equal, then P = 2 * (a + b), where a is the length, b is the width. Let’s calculate what is the second side of the rectangle.

a = 560/80 = 7 centimeters.

Let’s calculate what the perimeter of the rectangle is.

P = 2 * (80 + 7) 2 * 87 = 174 centimeters.

Answer: 174 centimeters.
