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

Hope it helps you ❣️☑️☑️

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
