The length of the rectangle is 9 cm, the width is 3 cm less. Find the area and perimeter of the rectangle.

Let’s find the width of the rectangle:

9 – 3 = 6 (cm) – the width of the rectangle.

The area of a rectangle is found as the product of width and length, we find it:

9 * 6 = 54 (cm2) – the area of the rectangle.

The perimeter is the sum of the lengths of all sides, this rectangle has two sides of 9 centimeters and two sides of 6 centimeters, we find their sum:

2 * 9 + 2 * 6 = 18 + 12 = 30 (cm) – the perimeter of the rectangle.

Answer: The perimeter of the rectangle is 30 cm, its area is 54 cm2.
