Question

Tiles have to be laid in two rooms of Neha's house. Each tile has

length 25 cm and breadth 15 cm. Find the number of tiles needed
for each room.
Room 1: length = 3 m, breadth = 2 m
Room 2: length= 4 m, breadth = 3 m

Answer 1

To find the number of tiles needed for two rooms, we first convert the room measurements to centimeters, calculate the area of each room, and then divide by the area of a single tile. Room 1 requires 160 tiles, and Room 2 requires 320 tiles, without considering partial tiles for any excess.

Step-by-step explanation:

We need to calculate the number of tiles needed for each room in Neha's house. First, we'll convert the dimensions of the rooms and tiles into the same units. Since the tiles are measured in centimeters, we will convert the room dimensions from meters to centimeters.

Room 1 has dimensions of 3 m x 2 m, which is equivalent to 300 cm x 200 cm. Room 2 has dimensions of 4 m x 3 m, which is equivalent to 400 cm x 300 cm. Each tile measures 25 cm in length and 15 cm in breadth.

To find the number of tiles needed for each room, we will calculate the area of each room and then divide by the area of a single tile.

Calculations for Room 1:

Area of Room 1 = 300 cm * 200 cm = 60000 cm2
Area of one tile = 25 cm * 15 cm = 375 cm2
Number of tiles for Room 1 = Area of Room 1 / Area of one tile
= 60000 cm2 / 375 cm2
= 160 tiles (not accounting for partial tiles)

Calculations for Room 2:

Area of Room 2 = 400 cm * 300 cm = 120000 cm2
Number of tiles for Room 2 = Area of Room 2 / Area of one tile
= 120000 cm2 / 375 cm2
= 320 tiles (not accounting for partial tiles)
