The length of the rectangle is 29 cm
According to the information given above,
A = [2, 4]
B = [5, 6]
A Intersection B = [1, 7]
The element of {A N B]! are those elements which are in both set A and set B with the exception of the elements that forms the intersection between them.
Thus, for the question given above,
