Please show me how to solve:

The length of a rectangle is 3 times the width. The perimeter is 44 cm. What are the dimensions of the rectangle?

  • math -

    x+x+3x+3x=44

    8x=44

    x=5.5

    L=3x=16.5cm

    W=x=5.5cm

  • math -

    width ---- x
    length ---- 3x

    2(x) + 2(3x) = 44
    the rest is easy.
