The perimeter of the rectangle is 24 cm and the length is 8 cm. Find the width of the rectangle.

To find the width of a rectangle, knowing its perimeter and length, you need to create and solve an equation.

The perimeter of a rectangle can be calculated using the formula:

P = 2 (a + b), where a and b are the length and width of the rectangle, and P is the perimeter.

Substitute the values specified in the condition into the formula and get the equation:

2 * (8 + b) = 24;

Divide both sides of the equation by 2:

8 + b = 24: 2;

8 + b = 12;

We are looking for a variable as an unknown term:

b = 12 – 8;

b = 4 cm.

The width of the rectangle is 4 cm.

Answer: 4 cm width of the rectangle.
