A rectangular piece of land has a length that exceeds its breadth by 20 metres. If fencing this land costs Rs. 5300 at a rate of Rs. 26.50 per metre, what is the length of the land in metres?
Explanation
Given the fencing cost and rate, the perimeter can be calculated as 5300 ÷ 26.50 = 200 metres. Let the breadth be x metres, then length = x + 20. The perimeter formula is 2(length + breadth) = 200, so 2(x + x + 20) = 200, which simplifies to 4x + 40 = 200. Solving for x gives x = 40 metres, so length = 60 metres. Since 60 is not among the given options, the correct choice is 'None of the above'.
