A perimeter

A perimeter of a parallelogram is 2.8 meters. The length of one of its sides is equal to one-seventh of the entire perimeter. Find lengths of the sides of the parallelogram.

Correct answer:

a =  0.4 m
b =  1 m

Step-by-step explanation:

p=2.8 m a=17 p=17 2.8=25 m=0.4 m
p=2(a+b)  b=p/2a=2.8/20.4=1 m
