Question

The cost of fencing a square field at ₹16 per m is ₹32000.Find the cost of reaping the field at ₹35m per 100 square metres.

Answer 1

• Price = Rs. 32000
• Rate = Rs. 16 per m

So

Perimeter = 32000/16 = 2000 m.

Perimeter = 4 x side

 ∴ '' Side ''       =  2000/4 = 500 m

Area = (side)²  =  500²  = 25 0000 m²

• Rate = Rs. 35 per 100  m²

Cost = 250000/100 x 35 =  Rs.87500

Answer 2

Here is your solution

Given :-

Price = Rs. 32000
Rate = Rs. 16 per m

So

Perimeter = 32000/16 = 2000 m.


Perimeter = 4 x side

2000/4 = side

500 m =side


Area of square = (side)²  =  500²  = 250000 m²

Rate = Rs. 35 per 100  m²

Cost of reaping the field = 250000/100 x 35 =  Rs.87500

Hope it helps you
