Question

The length of each side of a square is increased by 2 inches. If the perimeter is 20 inches, write an equation to show the original length of the side

Answer 1

The new length side of the perimeter, we'll call p. The original length, we'll call o. P's equation looks like this:

`p = 20 * (1)/(4)`
Since 5 is the length of one side, subtract 2 from 5 to get 3. The equation looks like this:

`o = (20)/(4) - 2`
or simply

`o = 5 - 2`
