A rectangular parking lot has a length that is 7 yards than the width. The area of the parking lot is 120 square greater yards. What is the length and the width?

Answer 1

#(7+w)*w=120# and w is 8 and l is 15 yards

Area of this lot is #w*l# where w is width and l is length.
Now you can write l as #l=w+7#

and solve your question

#120=(7+w)*w#
#120=7w+w^2#

or

#w^2+7w-120=0#

w is 8 and l is 15 yards. (I solved it by trial and error).

You can also solve it by quadratic equation solution.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
