"The length of a rectangle is 5 ft more than its width" means that the length is units. Since "its area is 84 square feet", we know that . Since we don't have to solve this, I'll leave it like this. If you wanted to solve, distribute and then get everything to one side. Once you have a simplified quadratic, use the quadratic formula to solve.
