Answer 1

1. 11cm

2.3meters 20cm

Explanation:

1. Avinash is 1.8m tall

Arun is 191cm tall

1.8m to cm= 180cm

Difference in their heights = (191-180)cm

=11cm.

2. Total length of 6ropes in cm= (19m×100)+20cm

=(1900+20)cm

=1920cm

Length of 1 rope = 1920cm÷6 ropes

=320cm

To meters = 320÷100

=3m20cm.
