Step-by-step explanation:
length of surface = 4 m or 400 cm
breadth of surface = 2.50 m or 250 cm
area of surface = l × b
= 400 × 250
= 100000 sq cm
size of tile is 10 × 10 cm
area of tile = 100 sq cm
tile required to cover the surface
= 100000/100
= 1000
therefore 1000 tiles are required to cover the surface
