The perimeter of a rectangle is 2(l+w).
The width is 1 so: 2(l+1)=10.
2l+2=10 ---> subtract 2 from both sides.
2l=8. -->Divide by 2 to isolate l.
L=4
Check:2(4+1)=10.
2*4=8
2*1=2
8+2=10
Length or V= 4
Hope this helps!

Answer: $1.50/cookie
Step-by-step explanation:
Cookies = x
Water = y
5x + y = $8.75
y = 1.25

5x = 8.75 - 1.25
5x = 7.50
x = 7.50/5
x = $1.50 for 1 cookie.
