# A parallelogram has sides with lengths of #15 # and #12 #. If the parallelogram's area is #45 #, what is the length of its longest diagonal?

the longest diagonal is26.4

Area of parallelogram = base . altitude

Further, the longest diagonal is given by the vectorial sum of the two adjacent sides

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.
