Tommy is very fond of rectangular shapes. In geometry class, Tommy was given four strips of paper to draw his favorite shape. Unfortunately, Tommy lost one strip and he still had & nbsp; three strips of paper
l1,
l2,
l3 . Now Tommy wondered if he could make a rectangle out of these strips if he cut any one strip once in such a way that the length of each part was non-zero, and the sum of the lengths of the resulting parts would be equal to the original length of the strip.
Tommy thinks a square is a rectangle.
Help Tommy see if he can make a rectangle.
