Question

The cost of fencing a square field at rupees 16 per metre is 32000.find the cost of reaping the field at 35 rupess per 100 metre square.

Answer 1

hello,
rate of fencing of square is 16/m
cost=32000
here,perimeter=cost/rate
=32000/16
2000m
hence,perimeter of square field is 2000m
now perimeter of square is 4×side
2000=4×s
s=500m
now area of square=side²
500²
250000m²
rate of reaping the field is 100/m²
cost=area×rate
cost=250000×100
cost= Rs.25000000
hope this helps,if u like it please mark it as brainliest

Answer 2

cost of fencing square field per metre = 16 rs
total cost = rs 32000

therefore perimeter of field = total cost / cost per metre
=> 32000/16 => 2000 m
therefore , side of square field = 2000/4 => 500 m

area of square field = s² => (500)² => 250000 m²

cost of reaping field per 100 m square = 35 rs
cost of reaping 1 m² = 35/100 => 7/20 rs
cost of reaping 250000 m² = 7/20 × 250000
=> 7×12500 => rs 87500
hope this helps
