Answer 2

Given, To find :

→ How many rectangular slabs of 10 cm × 8cm are required to cover the floor of a hall of 12m × 10m?

ㅤㅤ

Formula :

★ Area = Length × Breadth.

★ Number of labs = Area of floor/Area of all labs.

ㅤㅤ

Calculations :

→ Area = 10 × 8

→ Area = 80 cm² = 0.008 m²

ㅤㅤ

→ Area = 12 × 10

→ Area = 120

ㅤㅤ

→ Number of labs = 120/0.008

→ Number of labs = 15000 labs.

ㅤㅤ

★ Therefore, 15000 is total number of labs.
