and breadth 25m​

Answer 1

Answer:

hi

hope it will help you

Step-by-step explanation:

Area of the room(Ar) = length×width

Ar= 12×15m=180m²

but 1m²= 10000 cm²

180m²=1800000cm²

area of the square tile (As)=(length)²= L²

As=20cm×20cm=400cm²

no.of square tiles needed(n) =Ar/As

n=1800000/400=4500

thus,4.500 square tiles will be needed to build the floor of 12m×15m room
