The area of a rectangle is 45 square feet. The length is 4 feet longer than the width. Which equation could you use to find the length of the rectangle in feet?
Let the length be x+4 and the width be x:- Form a quadratic equation: (x+4)*x = 45 => x^2 +4x -45 = 0 Solving the equation: x has a positive value of 5 Therefore length is 5+4 = 9 feet and width = 5 feet Check: 9 times 5 = 45 square feet
If the length of a rectangle is 3 feet longer than it is wide then what would the equation be for the problem?
if you are trying to find the area then: width=x length=y y=3+x xy=area 3+x*x=area
