Answer:
Step-by-step explanation:
Length of rectangular hall = 1600 cm
Breadth of rectangular hall = 1200 cm
Area 1 = 1600 * 1200 cm^2 = 19,20,000 cm^2
Length of one slab = 25 cm
Breadth of one slab = 15 cm
Area 2 = 25 * 15 cm^2 = 375 cm^2
Therefore, no. if spans required =
Area 1 ÷ Area 2
=> 19,20,000 ÷ 375
= 5120 slabs
