i keep getting the question wrong

Answer:
C. 75
Step-by-step explanation:
1. Use the formula for the area of rectangle to find the length
[tex]A=lw[/tex]
[tex]344=l(16)[/tex]
[tex]21.5=l[/tex]
2. Use this value for the length to find the perimeter
[tex]P=2l+2w[/tex]
[tex]P=2(21.5)+2(16)[/tex]
[tex]P=43+32[/tex]
[tex]P=75[/tex]
