The perimeter of the rectangle is 48 cm. The length is 4 cm more than the width.

The perimeter of the rectangle is 48 cm. The length is 4 cm more than the width. Calculate the length and width of the rectangle.

The perimeter of a rectangle is the sum of its length and width times two. We will solve the problem using an equation with one unknown.

one). The width of the rectangle is x centimeters.

2). The length of the rectangle is (x + 4) centimeters.

3). Let’s compose and solve the equation.

(x + (x + 4)) * 2 = 48;

(x + x + 4) * 2 = 48;

(2x + 4) * 2 = 48;

4x + 8 = 48;

4x = 48 – 8;

4x = 40;

x = 40/4;

x = 10;

Answer: The width of the rectangle is x = 10 centimeters. The length of the rectangle is x + 4 = 10 + 4 = 14 centimeters.
