Question

Find the length of rectangular field , given that it's breadth is 50 metres and the cost of turfing it at rupees at rupees 41.25 per metre square is rupees 154687.50.

Answer 1

area of rectangular=2(length+breadth)

=2(x+50)

the cost of turfing for 1 meter square is 41.25

and the total area need 154687.50

then area= 154687.50/41.25=3750 meter square

then we solve

2(x+50)=3750

2x+100=3750

2x=3750-100

2x=3650

x=3650/2

x=1825meter

the length of the rectangular field is 1825 meter
