Given:
length of rectangular field= 75 m
breadth of rectangular field= (75-15)=60m
Therefore,
perimeter of field
=2(l+b)
=2(75+60)
=2×135
=270m
Cost of fencing at rate of Rs.4 per m
Hence, the cost of 270m of rectangular field= 270×4
=Rs.1080
And the cost of turfing at rate of Rs.7 per m
area of square=75×60=4500 sq.m
Cost of turfing= 4500*7
=Rs.31500

Answer: cost of fencing 1080 and cost of turfing 31500
Step-by-step explanation: Length is 75 meter
breadth will be 75-15= 60 m (as it is 15 m less than length)
perimeter formula is 2( length+ breadth)
perimeter will be 2( 75+60)= 270 m
rate of fencing will be 4*270=1080 rupees
area formula is length * breadth
area is 75*60= 4500 square meter
cost of turfing is 4500*7= 31500 rupees
