Answer:
1350
Step-by-step explanation:
Length = 9m = 9(100cm) = 900 cm
breadth = 6m = 6(100cm) = 600cm
Total area = area of rectangle
= length * breadth
= 900 cm * 600 cm
= 540000 cm²
Area of each tile = 40cm * 10cm
= 400 cm²
Let we need 'x' tiles to cover the total area.
area of 'x' tiles = area of floor
x * area of 1 tile = area of floor
x * 400 = 540000
x = 540000/400
x = 1350
Therefore, the required number of tiles is 1350.
