Q.

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?

View Answer

Correct choice: D

Explanation:

Let breadth = x metres. Then, length = (x + 20) metres. Perimeter =5300/23.50 2[(x + 20) + x] = 200 2x + 20 = 100 2x = 80 x = 40. Hence, length = x + 20 = 60 m.
