Answer 1

area of room =52sqm
area of room covered with carpet
=32.5sqm
area of room left un covered
52-32.5
=19.5sq m

Answer 2

given,
a room measures,
l = 8m
w= 6.5

a carpet measures,
l= 6.5
w=5m

area of the room
= l×b
= 8× 6.5m2
= 52.0 m2
= 52 m2


area of carpet,
= l×b
= 6.5× 5m2
= 32.5m2
now,
the area of the floor remain uncovered by carpet,

= the area of the room - area of the carpet
= (52-32.5 )m2
= ( 19 .5)m2
