The answer would be 6.412 × 10^4
Answer:
C
Step-by-step explanation:
This one I did already You're welcome
Area=l*b=l*(l-2)=80(given)
so, l^2 - 2l =80
l^2 - 2l - 80=0
l=10 or -8
l=10,b=10-2=8
perimeter=2(l+b)=2(18)=36
Eight goes into seventeen two times with one remaining, and since the denominator always stays the same,

would be your mixed fraction.
It’s 112:8 I’m pretty sure:)
