Brad knows the perimeter of his rectangular shaped patio is 24 feet. The width is 5 feet. How long is it?

**Perimeter of a rectangle is 2(width) + 2(length)**

**x = length**

2x + 2(5) = 24 {substituted into perimeter formula}

2x + 10 = 24 {multiplied}

2x = 14 {subtracted 10 from each side}

x = 7 {divided each side by 2}

**length is 7 ft**
