Question

The width of a rectangle is 3 inches shorter than the length. The perimeter of the rectangle is 18 inches. What is the length of the rectangle? a) 6 inches b) 7 inches c) 8 inches d) 9 inches

Answer 1

The length of the rectangle is 6 inches.

Step-by-step explanation:

The width of the rectangle is 3 inches shorter than the length. Let's assume the length of the rectangle is x inches. Therefore, the width would be x - 3 inches. The perimeter of a rectangle is calculated by adding all four sides together. In this case, the perimeter is given as 18 inches. So, we can set up the equation:

2(x + (x - 3)) = 18

Simplifying the equation, we get:

2(2x - 3) = 18

Solving the equation, we find that x = 6 inches. Therefore, the length of the rectangle is 6 inches.
