Answer:
x = 4
Step-by-step explanation:
12/15=28/a which is a=35 
then 35+28=63
14x+7=63 and x would be 4
 
        
             
        
        
        
X=4
First find the solution to (x+1) ft. I chose to guess the answer as 4 and it worked (you’ll have to guess). I then plugged 4 into the other equation 2x. It became 2•4. Solving give the side length of 8 ft. Then you have to check to make sure they both have the same area. To do this just solve the equations. 
First rectangle- 4•4= 16 ft area
Second rectangle- 2•8 = 16 ft area 
( I’m really sorry if this is confusing)
