The perimeter of a rectangle is 68 feet. Find the side length for x.

Answer:24
Step-by-step explanation:
You know one side of the rectangle is 8, which means the opposite has to also be 8. You then know two out of 4 sides. Using the same property, you know that the other two sides must also be equal.
8+8= 16
64-16= 48
48/2=24
