The length of a rectangle is twice its breadth. If its length is decreased by 5 cm and breadth is increased by 4 cm, the area of the rectangle is increased by 75 sq. cm. Find the length of the rectangle.	Choose the correct answer.
A) 20cm	B) 25cm	C) 26cm	D) 100/3cm	E) 23cm
Explanation:   Let breadth = x. Then, length = 2x. Then,   (2x - 5) (x + 4) - 2x * x = 75 =&gt; 3x - 25 = 75 =&gt; x = 100/3.   Length of the rectangle = 100/3 cm.   Answer: Option 100/3cm
