Question

The length of a rectangular plot is 20 metres more than its breadth. If the cost of fencing the plot @ 26.50 per metre is Rs. 5300, what is the length of the plot in metres?

Accepted Answer

Option E. None of these. Answer & Solution Answer: Option E Solution: & Let\, breadth = x\, metres & Then,\, length = \, ( x + 20 )\, metres & Perimeter = 530026.50 m = 200m & 2 [ ( x + 20 ) + x ] = 200 & 2x + 20 = 100 & 2x = 80 & x = 40 & Hence,\, length = x + 20 = 60m
