The formula to for finding the perimeter of the parallelogram is:-

[tex]P=2(a+b)[/tex]

Lets substitute and then solve:-

[tex]p = 2 (6.2 + 2.8)[/tex]

p = 2 (6.2 + 3.1)
p = 2 (9.3)
p = 18.6

So, the perimeter of this parallelogram is, p = 18.6 m (b).

Hope I helped ya!!  
perimeter
=2(6,2) + 2(3,1)
= 12,4 + 6,2
= 18,6 m
