Steps

Step 1 ：Given: Perimeter of Quadrilateral ABCD = 34 ft, AD = 12 ft

Step 2 ：We need to find the length of side CD.

Step 3 ： $P e r i m e t e r = A B + B C + C D + A D$

Step 4 ： $34 = A B + B C + C D + 12$

Step 5 ： $22 = A B + B C + C D$

Step 6 ：Insufficient information to determine the length of side CD.

Step 7 ： $I n s u f f i c i e n t i n f o r m a t i o n$
