Question

a field in the form of a parallelogram is to be ploughed using a rented plough .the charger for one hour is 300 and it can plough an area of 400 m2 per hour. if the length and corresponding height of the field are 80m and 50m respectively ,find the total cost of ploughing the field

Answer 1

Area of the Field =l*b
=80 *50
=4000

the rented plough can plough 400 m2=1 hour 
                                                4000 m2=x
x=4000/400=10
time =300*10=3000.
