Let the length and the width of the rectagular parking plot be "l" and the width be "w"

It is given that the length is 3 yards greater than the width.

That is

l = 3 + w and w = w

Also given that the area is 180 square yards.

The area of a rectangle is given by: A = l * w

180 = (3 + w)(w)

==>

==>

==>

==> (w + 15)(w - 12) = 0

==> w = 12, -15

Here the width cannot be negative. So we take the value of w as 12.

Hence, the length is w + 3

length = 12 + 3 = 15

Thus the length and the width of the rectangular parking plot is given by l = 12 and w = 3 yard

Hence, the solution.
