Answer:
The area of the shape (trapezoid) is 55 square feet. 
Step-by-step explanation:
The formula to get the area of a trapezoid is  . b1 is one of the bases, b2 is the other and h is the height.
 . b1 is one of the bases, b2 is the other and h is the height. 
First, you need to find the average of the bases: 
           (15+7=22)/2=11
Then, you multiply that by the height. 
           11*5=55
Lastly, you add the units. 
           55 square feet is the answer
 
        
             
        
        
        
Answer:
20+7x
Step-by-step explanation:
 you'd multiply 2 by 5 and 2 by 3x which will give you 10+ 6x; Then add the others : 2(5+3x)+(x+10) would be 10+6x+x+10 so its 20+7x.     .
