Explanation:
In a parallelogram, there are always two pairs of congruent sides.
That is, the perimeter of a parallelogram will always be the sum of twice the length, since there are two lengths, and twice the width, since there are two widths.
Hence the formula:
Manipulate the perimeter formula, given that
#P=2(l+w)#
#30=2(5+w)#
#15=5+w#
#w=10#
We can go back and check. If the sides of a parallelogram are
