Question

how many square tiles of size 10cm are require to cover the floor of a room whose length&breath are 1800 and1600 respectively​

Answer 1

Answer:

Step-by-step explanation:

Given

Length of the room=1800cm

Breadth of the room=1600cm

Side of the square=10cm

Let The total number of tiles be n

Perimeter of the room =n*Perimeter of square

2(l+b)=n×4(side)

2(1800+1600)=n×4(10)

2(3400)=n×40

6800÷40=n

170=n

Therefore 170 tiles are required
