Question

A FARMER OWNS A RECTANGULAR PLOT OF LENGTH 2 KM 500 M AND BREADTH 750M AND A SQUARE PLOT OF SIDE 1.5 KM . IF HE PUTS 1500 KG OF FERTILISER IN THE RECTANGULAR FIELD AND 1800 KG OF FERTILISER IN THE SQUARE FIELD,FIND-QUANTITIES OF FERTILISERPER KM SQUARE FOR EACH PLOT

Answer 1

Area of Rectangular plot = lb

                                        = 2.5 × 0.75

                                        = 1.875 km²

And so, Ratio that quantities of fertilisers per km = 1500/1.875

                                                                              = 800:1
_________________________________________________________

Area of Square plot = a²

                                = (1.5)²

                                = 2.25 km²

And so, Ratio that quantities of fertilisers per km = 1800/2.25

                                                                              = 800:1

Answer 2

Answer:

Area of Rectangular plot = lb

= 2.5 x 0.75

= 1.875 km2

And so, Ratio that quantities of fertilisers per km = 1500/1.875

= 800:1

4.0

Area of Square plot = a?

= (1.5)? =

= 2.25 km?

And so, Ratio that quantities of fertilisers per km = 1800/2.25
