Answers
Answer:
We know, 50cm=0.5m and
25cm=0.25m
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

Therefore, the room area is 15×8
=120m

The carpet area is 78m

The fraction of the area uncovered is
= 120 =120−78
= 120/42
= 20/7
