Let l be the length of the parcel of land. Recall that the area of a rectangle is the product of its length and width:

\(\displaystyle{A}={l}{w}\)

Substitute A=1125 square feet and w=25 feet:

\(\displaystyle{1125}={l}{\left({25}\right)}\)

\(\displaystyle\frac{{1125}}{{25}}={l}\)

\(\displaystyle{l}={45}\)

So, the length of the parcel of land is 45 feet.
