5. A tile is 15cm long and 10cm wide. The four walls of the kitchen need to be tiled. If the length and
breadth of each wall is 440cm and 750cm, how many tile will be required to tile the entire kitchen?​

Answer 1

Step-by-step explanation:

area = length × breadth

= 15×10

= 150 cm²

Area of tiles = 150 cm²

area of one wall = length× breadth

= 440 × 750

= 330000 cm²

area of four walls = 330000 × 4

= 1320000 cm²

Number of tiles required =

1320000÷150

=8800 tiles

Ans. 8800 tiles are required to tile the entire kitchen.
