5. Vineet wants to polish the floor of a room which is 140 cm long and 120 cm wide
The charges for polishing the floor is 52 per square metre. What will be the cost of
polishing the floor of the room?​

Answer 1

Answer:

Length=140cm

Breadth=120cm

Area=l×b

140×120=16800sq.cm

=1.68

cost for polishing the room=1.68×52 (cost of per square meter)

=87.36

Answer 2

Step-by-step explanation:

Given: length of the floor ( l ) = 140cm = 1.4m

breath of the floor ( b ) = 120cm = 1.2m

cost of 1m² = 52

Area of the floor ( Ar ) = l × b

Ar = 1.4m × 1.2m

Ar = 1.68m²

Now, we know that cost of 1m² = 52

So, cost of floor = 1.68m² × 52

cost of floor = 87.36
