Length of a rectangular plot is 22 mtr more than its breadth. If the cost of fencin gthe plot at 26.50 per meter is Rs. 5300, what is the length of the plot in mtr? Choose the most appropriate option:
A) 51 m	B) 61 m	C) 71 m	D) 81 m	E) 91 m

Rationale: "let breadth = x metres . then , length = ( x + 22 ) metres . perimeter = 5300 m = 200 m . 26.50 2 [ ( x + 22 ) + x ] = 200 2 x + 22 = 100 2 x = 78 x = 39 . hence , length = x + 22 = 61 m b"
Answer: B
