25p in rupees=₹0.25
area of rectangular field =1000/0.25=4000m²
lenght*breadth=4000
lenght=4000/50=80
if the lenght increases by 20m,
lenght=80+20=100m
breadth=50
area of new rectangular field=100*50=5000m²
cost of grassing of new rectangular field=5000*0.25=1250m²

Answer:1250m²
Step-by-step explanation:
25p in rupees=₹0.25
area of rectangular field =1000/0.25=4000m²
length×breadth=4000
length=4000/50=80
if the length increases by 20m,
lenght=80+20=100m
breadth=50
area of new rectangular field=100×50=5000m²
cost of grassing of new rectangular field=5000×0.25=1250m²
