Answer:
Susan is 8
Step-by-step explanation:
Lisa: 16
Susan: 11
John m: 23
Susan: s
Lisa: s+5
John: s+5+7 = s+12
s + s+5 + s+12 = 50
3s + 17 = 50
3s = 33
s = 11
s+5 = 16
s+12 = 23
around 73-89%
Hope this helps!
The answer is C. So yeah.
D) L=50 W=50
Just "plug and chug" these numbers and see which doesn't work.
A is not it, 20+30=50 (then *2 because we need 4 sides not just 2) 50*2=100
B isn't it, 10+40=50*2=100
C ain't it either 49+1=50*2=100
D is the answer 50+50=100*2=200
