Ans. Length of the plot = 28 m,

Breadth of the plot = 18m

Area of the rectangular plot = 28m × 18m = 504 m2 

Length of outside rectangle = 28+ 1 + 1 = 30m,

Breadth of outside rectangle = 18 + 1 + 1 = 20m
Area of outside rectangle = 30  × 20 = 600 m2 

Area of foot path = 600 - 504 = 96 m2 = 96 × 100 × 100  = 960000 cm2 

Area of the square tile = 40 × 40  = 1600cm2

The number of tiles = Area of Path / Area of tiles = 960000 /1600 = 600
