Hello!
To solve this, we will use substitution and a system of equations where L=length and w=width.
66=2L+2w
L=3w-3
We know that L=3w-3, so we will plug it into the first equation to find w.
66=2(3w-3)+2w
66=6w-6+2w
66=8w-6
72=8w
9=w
Now that we know what w equals, we will plug it into the second equation to find the length.
L=27-3
L=24
We have our numbers, but let's check with the first equation.
66=48+18
66=66
The length is 24, and the width is 9.
I hope this helps!
