Question

the cost of fencing a square field at rupees 16 per metre is rupees 32000 find the cost of repairing the field at rupees 35 M 100 m square

Answer 1

perimeter of square field=total cost/rate of fencing
4 x side length=32000/16
4 x side length=2000
hence side length=500 m
now area of square field=(side length)^2
=(500)^2
=250000 m^2
cost of reaping the field=rate of reaping x area of square field
=35/100 x250000
=35 x 2500=87500 Rs

Answer 2

Answer:

Step-by-step explanation:

Perimeter of field= total cost÷ rate

=32000÷16

=2000m

Side of field =perimeter/4

=2000/4

=500m

Area of field = side× side

= 500m X 500m

=250000 sq m

Cost of repairing 100 sq m = Rs 35

Cost of repairing 1 sq m. =

Rs35/100

Cost of repairing the field =

35×250000/100

=Rs 87500
