Question

find the perimeter of a rectangle having Length = 8m and breadth = 9dm​

Answer 1

Answer:

perimeter of a rectangle is

2(l + b)

1 dm = 0.1 m

so

9 dm = 0.9 m

so now

2 ( .1 + .9)

= 2 (  1 )

=  2 meter

so  meter is the perimeter

Answer 2

Answer:

17.8m

Step-by-step explanation:

We know that,9dm=.9m

perimeter of a rectangle =2(length+breadth)

=2(8+.9)m

=2×8.9m

=17.8m
