Solve by setting up the proper equation to describe the facts given and then carrying out the mathematical calculations to solve for the unknown variable(s).
The length of a rectangle is 3 times the width. The difference between the length and the width is 8 feet. Determine the rectangle’s length

  • ALGEBRA -

    let the width be x
    then the length is 3x

    3x - x = 8
    2x = 8
    x = 4

    width is 4 ft
    length is 12 ft
