If you use the law of sins, the answer would be B) 6.928 (in the law of sines you round so it would be 6.93)
Perimeter is the addition of all 4 sides and a square as all the same sides. so every side will be the same. so if you divide 216 by 4 you get 54. you can check this by adding 54+54+54+54=216 or 54x4=216
Per half gallon it is $2.25
1/2 G=$2.25
1 G=$4.50
1 1/2 G=$6.75
And so on...
Hope this helped
You would have 4 left after dinner: (.875)(32)=28 so you have 28 completed before dinner and would have 4 left to do.
