Answer:


5c^2+2cd-2d^2-15

Explanation:

To solve this problem, we must add up all the side values.

Our equation for the perimeter will look like:


side1+side2+side3+side4=perimeter

Now lets plug in our values for our sides and solve:


4c^2+4cd+12+c^2-d^2+1+3cd+4d^2-30-5d^2-5cd+2=perimeter

Now lets combine like terms:


5c^2+2cd-2d^2-15

So this is our perimeter!

Hope this helps! :3
