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.
