    A garden has a length that is three times its width. If the width is n feet and fencing cost $8 per foot, what is the cost of the fencing for the garden?

    Garden is a rectangle which has Perimeter P of:
    P = 2l + 2w
    l = 3w
    P = 2(3w) + 2w
    P = 6w + 2w
    P = 8w

    Width w = n, so we have:
    P = 8n

    Cost = 8n * 8 = 64n dollars
