The perimeter of a rectangle is the sum of all of its sides. The standard equation would be: P=2L%2B2W

If the lenght is 3 inches greater than its width, let:
x = width
x+3 = lenght

Our equation then becomes: 24=2%28x%2B3%29%2B2x

Now solve for x to find the width; add 3 to find the length.

Always check your answers by plugging the values in the original equation. You need to come up with 24 inches.
