A rectangular piece of 150 sq m has a length which is 1m more than the 4 times the breadth. What is the perimeter of the piece?  Answers.
A) 60 m B) 61 m C) 62 m D) 63 m E) 64 m
Let its breadth be = x m.   So length will be = (4x+1) m.   Now,   x * (4x+1) = 150   or, 4x^2+x-150 = 0   or, (4x+25)(x-6) = 0   Either 4x = -25 or x = 6   As breadth can not take negetive value so x = 6   So its length is   4*6+1=
