Answer:
4
Step-by-step explanation:
2L=w
32=LxW
so you put the 2L as the w
which is 32=Lx2L
32=2L^2
16=L^2
4=L
*To find the width you input 4 as L*
So 8=W
The shortest side would be 4

Ok so lets say we have a system of equations:
y = x + 1
x + y = 5
All you would do is plug in what is equal to the variable so:
x + x + 1 = 5
Then you would just simplify and solve
2x + 1 = 5
-1 -1
