Step-by-step explanation:
We know, 8cm=0.08m and
20cm=0.20m
Tiles along the length of the room=
0.5
15
= 30 tiles
Tiles along the length of the room=
0.25
8
=32 tiles
Total number of tiles required =30×32 =960 tiles
To leave 1m between the carpet and wall on all sides, the carpet needs to be 2m shorter in each dimension.
Therefore,
(15−2)m(8−2)m
=(13×6)m
=78m
2
Therefore, the room area is 15×8 = 120m
2
The carpet area is 78m

The fraction of the area uncovered =
120
120−78
=
120
42
=
20
