Question

A carpet is laid on the floor of a room 8m by 5m leaving a border0.5m wide all round it,, then the perimeter of the. carpet is

Answer 1

For carpet without border

l = 8m
b = 5m

Carpet with border
l = 8m
b = 0.5m for one side
Total b will be 2 (0.5)
= 1
b = 1

Total b = 5m + 1m = 6m
Total l = 8m + 1m = 9m

Perimeter = 2 (9m + 6m)
= 2 (15)
= 30m

Answer is 30m

Answer 2

heya frnd!

here's ur answer...

given the length of the floor is 8m and breadth is 5m.if the carpet is laid on the floor leaving border of 0.5m then:-

the length of the carpet=8-(0.5+0.5)

=8-1

=7m

breadth of the carpet=5-(0.5+0.5)

=5-1

=4m

therefore perimeter of the carpet=2(l+b)

=2(7+4)

=2×11

=22m

hope this helps..!
