Answer:
120 feet
Step-by-step explanation:
Length/height =second number in ratio (here's it is 12)
L/10=12
Therefore length will be 120
First we have to divede the tota of students into the sice of each grop so:

So we can aproximate this to a whole number so:
√3=1.7
2√3=3.4
√5=2.2
The order:
√3,2√3,√5
G+b=5716
65g+40b=341690
multiply first equation by -65
-65g-65b=371540
add that to 2nd equation
-65g-65b=-371540
<span><u>65g+40b=341690 +</u></span><u />
0g-25b=-29850
-25b=-29850
divide both sides by -25
b=1194
latter=bleacher=1194 tickets
