    The new area would be 602,000 yd².

    When you enlarge a shape (or a park) by a factor, you are multiplying the length of its sides by that factor. In this case, we are multiplying its length and width by 4.

    Let l be the old length and w be the new length. The old area would be given by A=lw.

    Enlarging this by a factor of 4 would make the new length 4l and the new width 4w. The new area would be 4l (4w) = 16lw. The new area is 16 times larger than the old area, so:

    37,625 (16) = 602,000.
