Answer:
number of tiles needed = 2500 pieces
Step-by-step explanation:
Floor area = 5m x 20m = 100 m²
area of 1 square tile = 20cm x 20cm = 400 cm² ---- convert to m²
400 cm² x [tex]\frac{1 m^{2} }{100^2 cm^2}[/tex] = 0.04 m²
To get the number of tiles required to cover the floor area 5x20 = 100 m²
just divide it by the area of tile.
so Number of tile req'd = 100 / 0.04 = 2500
therefore,
the number of tiles needed = 2500 pieces
