Answer:
625 tiles
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Total room floor area = 16 × 12 = 192
So, area of one third room = 192 × (1 ÷ 3)
Area of one third room = 64
Length of each tiles = 0.32
As it is a square tile, width = length, = 0.32
o, total area of each tile = 0.32 × 0.32 = 0.1024
So, number of tiles to cover 64 area of room = 64 ÷ 0.1024 = 625 tiles.
Hence, 625 tiles needed to cover one third of room.
