The area of a rectangular field is 144 m2. If the length had been 6 metres more, the area would have been 54 m2 more. The original length of the field is Select:	A) 22 metres	B) 18 metres	C) 16 metres	D) 24 metres	E) None of these
Let the length and breadth of the original rectangular field be x m and y m respectively.   Area of the original field = x × y = 144 m2   ∴ x = 144⁄y .....(i)   If the length had been 6 m more, then area will be   (x + 6) y = 144 + 54   ⇒ (x + 6)y = 198… (ii)   Putting the value of x from eq (i) in eq (ii), we get   (144⁄y + 6)y = 198   ⇒ 144 + 6y = 198   ⇒ 6y = 54 ⇒ y = 9m   Putting the value of y in eq (i) we get x = 16 m   Answer 16 metres
