The length of a rectangle pillow is twice its breadth. If its length is decreased by 25cm and breadth is
increased by 25 cm, the area of the rectangle is increased by 375sq. cm. Find the length of the rectangle.

OPtion

1) 100 cm
2) 80cm
3) 75cm
4) 55cm
5) 66cm
6) 85cm
7) 72cm
8) 66cm
9) 61cm
10) None of the above

Solution

Let breadth = x. Then, length = 2x Then,
(2x -25) (x + 25) - 2x * x = 375
50x – 25x- 625= 375
25x = 1000
x = 40
Length of the rectangle = 2x = 80 cm.
