Answer:
Both left and right sides of the equation are equal
Step-by-step explanation:
suppose a rectangle is a quadrilateral with the parallel sides equal
one of the side is named as "l" while other is named as "w"
now according to the definition perimeter is the sum of all the sides of a quadrilateral so the equation can be written as
p= w+l+w+l --------(1)
now performing the arithmetic operation i.e addition in the equation and the equation becomes
p=l+l+w+w (rearranging the 1)
p=2l+2w
taking 2 as common the equation becomes
p=2(l+w)
hence the problem is solved
