Question: The difference between the length and the perimeter of a rectangle is 100 cms. What is the breadth of the rectangle?Solution:Let the length of the rectangle be 'x' and breadth of the rectangle be 'y'According to the question:2(x + y) - x = 100⇒ 2x + 2y - x = 100⇒ x + 2y = 100From this we cannot find 'y' (breadth), so the given data is inadequate.
