The perimeter of a square is 500 inches. How long is each side?

125 inches per side

Step-by-step explanation:

To work out the perimeter, you have to add all of the measurements of each side together. We already know that the shape is a square, meaning that all the sides are the same length. So if you divide the 500 inches by 4 (because there are 4 sides to a square) you get the answer 125 inches per side.

To double check this is right, you can do the reverse question. To do this you just add 125 four times (125 + 125 + 125 + 125) which should give you the answer 500, which was where we started

500 divided by 4 (as a square has 4 sides) = 125cm
