The length of a rectangle in 18 inches. What is the perimeter of the rectangle if the length is 7 incheslonger than the width?
P = 2L + 2W
P = (2 * 18) + 2(18 - 7)
P = 36 + 22
P = ?
thank you!
You're welcome.
To find the perimeter of a rectangle, we need to know both the length and width of the rectangle. In this case, we are given that the length of the rectangle is 18 inches and it is 7 inches longer than the width.
Let's define the width of the rectangle as "w". Since the length is 7 inches longer than the width, the length would be "w + 7".
The perimeter of a rectangle is calculated by adding the lengths of its four sides. We know that the opposite sides of a rectangle are equal in length.
So, the perimeter can be calculated as follows:
Perimeter = 2(length + width)
Substituting the values, we get:
Perimeter = 2((w + 7) + w)
Simplifying further:
Perimeter = 2(2w + 7)
Perimeter = 4w + 14
Therefore, the perimeter of the rectangle is 4w + 14.
However, we still need the value of the width ("w") to compute the exact perimeter. If the width is provided, we can substitute it into the equation to find the perimeter.
