Find the dimensions of a rectangle having an area of 10 square centimeters and whose width is 3 centimeters less that its length.

  • math -

    Let x = length, then width = x-3.

    Area = Length * Width

    10 = x(x-3) = x^2 - 3x

    x^2 -3x -10 = 0

    (x-5)(x+2) = 0

    Take it from here.
