Question

A room has a floor with length 13m 25cm and breadth 10m 85cm what is the perimeter of the floor ?​

Answer 1

perimeter of the floor

= 2 * (13.25 + 10.85)

= 2* 24.10

= 48.20 m

= 48 m 20 cm

Answer 2

Answer:

Floor length:-

13m25cm.

(we know that:-1m=100cm .i.e,1cm =1/100m)

So,

13m+25/100m=13+0.25=13.25m

Floor breadth:-

10m85cm

(we know that:-1m=100cm .i.e,1cm =1/100m)

So,

10m+85/100m=10+0.85=10.85m

Perimeter of the floor=2(length+breadth)

=2(13.25+10.85)

=48.2m
