Can u guys answer this question asap.

a farmer spreads 25 kg of fertiliser over an area of 4000m square. how much fertiliser would be needed to cover an area of 1.5 ha

93.75 Kg

Step-by-step explanation:

Farmer spreads 25 kg fertilizer over an area of 4000 m square .

So, Over 1 m square , kg of fertilizer will be needed

As we know , 1 hectare = 10,000 m square.

So, 1.5 hectare equals 15,000 m square.

So, for 15,000 m square , Fertilizer needed will be equal to                                       ×15,000 = 93.75 Kg

So, 93.75 Kg of fertilizer is needed for 1.5 ha of land.

The size of the augmented matrix for this system is:

                          2×3

We are given a system of linear equation consisting of two variables L and S as:

Hence, the system that is formed is:

where

and

and the augmented matrix is written as:

Hence, the size of the augmented matrix for this system is:
