    Area is multiplied by 4.

    Step-by-step explanation:

    The area of rectangle with dimensions h and l are h*l.

    If we multiply the height, h, by 4 we get the dimensions are 4h and l, and so the new area would be (4h) * l or 4hl or 4 (hl). So the area would be 4 times as much as it was before.
