be used to cover the floor of the room with are
128 m². How many such tiles are required?
​

Answer 1

Answer:

400 tiles

Step-by-step explanation:

$area \:of \: a \: parallelogram = base \times height$

Given;

base=80cm=0.8m

height=40cm=0.4m

area of 1 tile = 0.8×0.4 = 0.32 m^2

area of room = 128 m^2

No. of tiles required = area of room/area of 1 tile

=128/0.32=400 tiles
