It is given that the garden is 90\; m long and 75\; m broad

It is clear that it is rectangular shaped with lenght = 90 \ m \ and \ breath = 75 \ m

We know that the area of the rectangle is = lenght \times breath

\Rightarrow lenght \times breath = 90 \times 75 = 6750 \ m^2 = 0.675 \ ha                   -(i)

Now, length and breadth of the outer rectangle is



Area of the outer rectangle is 

\Rightarrow lenght \times breath = 100 \times 85 = 8500 \ m^2                              -(ii)

Area of the path is (ii) - (i)

\Rightarrow 8500 - 6750 = 1750 \ m^2

Therefore, the area of the path is 1750 \ m^2
