(a) Quantities of fertiliser per km for each plot.
​

Answer 1

answer :

area of the rectangular plot :

2km 500m=2.5 km

750m= 0.75km

area= length ×breeath

area =2.5×0.75=1.875km²

find the area of the square plot:

area = length× breath

area = 1.5 × 1.5 = 2.25km²

amount of fertilizers in the rectangular plot :

total fertilizer= 1500kg

1.875km²= 1500

1km²= 1500÷. 1.875= 800kg amount of fertilizer in the square plot :

total fertilizer = 1800kg

2.25 km²= 1800kg

1km²= 1800÷ 2.25 = 800kg
