The length of the rectangle is less than one decimeter by 2 cm. What is the width of this rectangle

The length of the rectangle is less than one decimeter by 2 cm. What is the width of this rectangle if its perimeter is 24 cm? find the area of a rectangle.

1. Determine the size of the length of the rectangle.

10 – 2 = 8 centimeters.

2. Suppose the width of the rectangle is x centimeters, using the formula by which we calculate the perimeter of the rectangle, compose an equation and determine its value.

(x + 8) * 2 = 24;

2x + 16 = 24;

2x = 24 – 16 = 8;

x = 8/2 = 4 centimeters.

3. Let’s calculate what is the area of this rectangle.

8 * 4 = 32 cm².

Answer: Width – 4 centimeters, area – 32 square centimeters.
