Answer:
the length should be 28.5 cm.
Step-by-step explanation:
i used the equation 2L+2W=P (or L+L+W+W=P)
(length + length +width + width = perimeter)
I plugged the given information into this equation so i had:
2L+(2L-14)=86
then i solved for L
(this is what that work would look like if you need it):
2L + 2(L - 14) = 86
1. distribute the 2 in 2(L-14):
2L + 2L - 28 = 86
2. combine like terms:
4L - 28 = 86
3. add 28 to both sides:
4L = 114
4. divide both sides by 4
L = 28.5
hope this helped :)
Vertical location, answer b
84,000/15 = 5600
2 x 5600 = 11,200
The first person will get $11,200

I don't know if this is right but i think the answer is 11 because as the number of people in the group goes up the price keeps decreasing by 3 so I made a table to see the difference...
1=42
8=39
9=36
10=33
11=30
