How many square tiles of side 16 cm will be required to pave the floor of a rectangular room 6.4 * 5 m?
Answers
Given: Length of the floor(l) = 6.4m
Breadth of the floor(b) = 5m
Side length of the square tile(s) = 16cm
Area of the rectangular floor = l × b
= 6.4 × 5
= 32m2 = 320000cm2 (since, 1m2 = 10000cm2)
Area of a square tile = s × s
= 16 × 16
= 256cm2
Number of tiles required = Area of the rectangular floor / Area of a square tile
= 320000/256
= 1250
Step-by-step explanation:
dimensions of rectangular floor = 6.4m × 5m
area of rectangular floor = length × width
= 6.4 × 5
= 32m^2
= 320000cm^2
one side of square tile = 16cm
area of one square tile = 16 × 16
= 256cm^2
number of square tiles needed to pave the rectangular floor = 320000 ÷ 256
= 1250 tiles
