Q.1 A garden is 90 m long and 75 m broad. A path 5 m wide is to be built outside and around it. Find the area of the path. Also find the area of the garden in hectare.

= 90 m × 75 m = 6750$$m^2$$
= 100 m × 85 m = 8500 $$m^2$$
Area of the path = 8500 $$m^2 – 6750 m^2 = 1750 m^2$$
Hence, required area of path = $$1750 m^2$$ and area of the garden =$$6750 m^2 = 0.675 hactare$$
