What is the least number of square tiles required to pave the floor of a room 15 m 17 cm long and 9 m 2 cm broad?

  • 1840
  • 2841
  • 3820
  • 4814
Answer:- 1
Explanation:-

Solution:
Length of the room = 15 m 17 cm = 15 * 100 + 17 = 1517 cm.
Breadth of the room = 9 m 2 cm = 902 cm.
The HCF of the 1517 and 902 will be size of square tiles.
HCF 1517 and 902 = 41 cm.
Area of the room = length × breadth = 1517 × 902 cm2.
Area of tiles = 41 × 41 cm21
So, no. of tiles required =
1517×90241×41
  = 814 tiles
