Question

a rectangular field is being grassed at the rate of 25 p/m2 for which a sum of 1000 rs is spent.The breadth of field is 50 m.If the length is increasedby 20 m.What is the new expenditure?

Answer 1

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

PLEASE MARK AS BRAINLIST ANSWER IF IT IS CORRECT.

Answer 2

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
