Question

A floor space, in the form of a parallelogram with a base of 5.4 m and a height of 7 m, is to be filled with
parallelogram tiles, each with a base of 20 cm and a height of 50 cm. How many such tiles will be needed for
the floor space?

Answer 1

Step-by-step explanation:

height of a parallelogram floor space = 7 m

base of a parallelogram floor space = 5.4 m

therefore, area of parallelogram floor space = b×h

= 5.4 × 7

=37.8 sq. m

converting cm into m

100cm =1 m

therefore , 20cm = 20÷100=0.2 m

50cm = 50÷100= 0.5 m

base of a parallelogram tiles= 0.2m

height of a parallelogram tiles= 0.5m

therefore , area of parallelogram tiles= b×h

=0.2×0.5

= 0.1

tiles required for parallelogram floor =

area of parallelogram ÷ area of tiles

=37.8 sq.m ÷0.1 sq. m.

=378 tiles .

Tiles needed for floor space = 378 tiles .
