I found width=13.72 ft and length=43.72 ft.
Call one dimension of the rectangle x, the other will be x+30
You want an area A=600 ft^2 but A=length x width=x*(x+30)=600
Rearranging you get:

solving this quadratic equation you get a negative solution and a positive one that gives your result.
Answer:
248°
Step-by-step explanation:
y = 180°- 56°
= 124°
x = 124° because opposite angles of a parallelogram are equal
x + y = 124° + 124°
= 248°
