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
