Question

A courtyard is 4.8 m by 3.2 m.Its floor is to be constructed with tiles measuring 10cm×10cm .Find the number of tiles required to cover the floor

Answer 1

Answer:

area of courtyard (rectangle) = L×B

=(4.8×3.2)m

=15.36 sq m

10 cm express as meter = 10/100m

= 0.10m

area of square (tile) = side × side

= (0.10×0.10)m

=0.01 sq m

number of tiles are required = 15.36/0.01

=1536 tiles
