Question

the length and breadth of a rectangular floor are 10 meter and 8 meter respectively . How many square tiles will be needed to cover the floor , if the sides of a tile is 50 cm.

Answer 1

3.2 tiles

Explanation:

first we find the area of the rectangular floor which is

length x breadth

10x8 = 80m^2

now we find the area of 1 square tile

side x side

50x50 = 2500

we convert 2500 into meters

2500/100 = 25

now we divide the area of the rectangular floor with the area of 1 square tile and we get

80/25 = 3.2 tiles
