3. A city street parking spot has a perimeter of 256 feet. The parking spot has side lengths of 17 feet; 52 feet; 18 feet; and 29 feet. What is the length of the missing side?

To find the length of the missing side of the parking spot, you can use the formula for the perimeter of a polygon, which is the sum of all its sides. The given perimeter is 256 feet and the sides are 17 feet, 52 feet, 18 feet, and 29 feet. First, you add the lengths of the known sides: 17 + 52 + 18 + 29 = 116 feet. Now, subtract that sum from the total perimeter to find the missing side: 256 - 116 = 140 feet. So, the length of the missing side is 140 feet! Easy as pie! 🍰
