    w - width

    2w - length (l)

    30 cm - perimeter

    w + w + 2w + 2w = 6w - perimeter

    The equation:

    6w = 30 divide both sides by 6

    w = 5 cm

    2w = 2 (5) = 10

    l = 10 cm

    The area of a rectangle: A = lw.

    Substitute:

    A = (5) (10) = 50

    Answer: The area is 50cm²
