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? 40 50 120 none of these

Answer 1

Answer:

rate*2(l+b)=5300

Step-by-step explanation:

Answer 2

Let breadth = x metres.

Then, length = (x + 20) metres.

Perimeter = 5300 m = 200 m.

26.50

2[(x + 20) + x] = 200

2x + 20 = 100

2x = 80

x = 40.

Hence, length = x + 20 = 60
