Please read the explanation.
Step-by-step explanation:
Background
You have a rectangular field and you need to fence it. This means you need to put a fence around the field. The length of the fence will be equal to the perimeter of the rectangular field.
Interpretation
"The cost of fencing a rectangular field at Rs.7.50 per metre is Rs.600"
By rate we mean the cost for one unit. In this case, it means that it will cost Rs.7.50 to put up a fence of 1 metre. At this rate, the total cost of fencing is Rs.600.
Calculations
Total cost of fencing (Rs.) =
Rate of fencing (Rs. per metre) * Length of fence (in metre)
In our example, let length of the fence = "x"
=> 600 = 7.50 * x
=> x = 600/7.50
=> x = 80
The length of the fence is 80m. This is equal to the perimeter of the rectangular field.
