The perimeter of a rectangle equals the sume of the lengths of its four sides. If the width of a rectangle is 9 inches and its perimeter is 52 inches, find the length of the rectangle.

P = 2L + 2W

52 = 2L + 18

52 - 18 = 2L

34 = 2L

24/2 = L

find the unknown side. The area of the rectangle is 126 square centimeters one side is 7 cm what is the value of x.

To find the length of the rectangle, we can use the formula for the perimeter of a rectangle, which is given by:

Perimeter = 2 * (Length + Width)

Given that the width is 9 inches and the perimeter is 52 inches, we can substitute these values into the formula and solve for the length.

52 = 2 * (Length + 9)

To solve for Length, let's start by simplifying the equation:

52 = 2 * Length + 2 * 9

52 = 2 * Length + 18

We can then isolate 2 * Length by subtracting 18 from both sides of the equation:

52 - 18 = 2 * Length

34 = 2 * Length

Dividing both sides of the equation by 2 gives us:

Length = 34 / 2

Length = 17

Therefore, the length of the rectangle is 17 inches.
