Question

please i need serious help with this question i have no idea how to do it

Answer 1

Answer:

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

Step-by-step 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
