Answer:
[tex]5c^2+2cd-2d^2-15[/tex]
Step-by-step explanation:
To solve this problem, we must add up all the side values.
Our equation for the perimeter will look like:
[tex]side1+side2+side3+side4=perimeter[/tex]
Now lets plug in our values for our sides and solve:
[tex]4c^2+4cd+12+c^2-d^2+1+3cd+4d^2-30-5d^2-5cd+2=perimeter[/tex]
Now lets combine like terms:
[tex]5c^2+2cd-2d^2-15[/tex]
So this is our perimeter!
Hope this helps! :3
