Final answer:
To find the width of the parking space with a given perimeter of 54 feet and length of 18 feet, we use the perimeter formula of a rectangle, yielding a width of 9 feet.
Step-by-step explanation:
To find the width of the parking space, we can use the formula for the perimeter of a rectangle: Perimeter (P) = 2 × (length + width). The problem gives us the perimeter as 54 feet and the length as 18 feet. Therefore, we can set up the equation:
54 = 2 × (18 + width)
Dividing both sides by 2 to isolate the sum of length and width we get:
27 = 18 + width
Subtracting 18 from both sides to solve for the width, we get:
width = 27 - 18
width = 9 feet
So, the width of the parking space is 9 feet.
