5c^2+2cd-2d^2-15
Step-by-step explanation:
Hello, to find the perimeter of any shape, you just add all the side together. In this picture, you would add all the sides up like this:
4c^2+4cd+12+-5d^2-5cd+2+c^2-d^2+1+3cd+4d^2-30
Then, combine like terms (add all of the numbers with the certain variable together) and you would get the answer which is:
5c^2+2cd-2d^2-15
What are the options that you can choose from???
