Bol Wants to cover a room 3 m 50 cm wide and 6 m long by squared tiles

1.	Bol Wants to cover a room 3 m 50 cm wide and 6 m long by squared tiles. If each square tile isside 0.5 m, find the number of square tiles needed to cover the floor
Answer» Area of floor = length * breadthFloor Length= 3.5 m, Breadth = 6 mArea of floor Af = 3.56 = 21 m^2 Area of tile = sidesideTile side length = .5 mArea of tile At = .5.5 =.25 m^2 Let number of tiles needed be nThen, nAt = Afn.25 = 21n = 214 = 84 Number of tiles needed = 84

Answer»

Area of floor = length * breadthFloor Length= 3.5 m, Breadth = 6 mArea of floor Af = 3.5*6 = 21 m^2

Area of tile = side*sideTile side length = .5 mArea of tile At = .5*.5 =.25 m^2

Let number of tiles needed be nThen, n*At = Afn*.25 = 21n = 21*4 = 84

Number of tiles needed = 84
