Question
The length of a rectangle is twice its breadth. If its
length is decreased by 6 cm and breadth is increased by 6 cm, the area of the rectangle is increased by 84 sq.cm. Find the breadth of the rectangle.Solution
Let the breadth of a rectangle = x cm And the length of a rectangle = 2x cm According to the question, => (2x – 6) (x + 6) – 2x x x = 84 => 2x2 + 12x – 6x – 36 – 2x2 = 84 => 6x = 120 => x = 20 Breadth of the rectangle is = x = 20 cm
