Answer:
Omar should weigh 9 pounds and 7 ounces
Step-by-step explanation
Each pound is equal to 16 ounces. So with 5 ounces each week for 4 weeks in all, you get a total of 20 ounces. Add the first 3 to get 23 before taking away 16 ounces to add another pound to the 8. This leaves you with 7 ounces. SO Omar should weigh 9 pounds and 7 ounces after 4 weeks.

Width=x-6
lenght=x
Perimeter of a parallelogram=2(lenght)+2(width)
Data:
Perimeter=60 m
Therefore:
2(x)+2(x-6)=60
2x+2x-12=60
4x=60+12
4x=72
x=72/4
x=18
Width=x-6=18-6=12
Lenght=x=18
Answer: the lenght would be 18 m, and the width 12 m
