Answer:  Option b.
Step-by-step explanation:
 First, you need to calculate the ratio of the area. This is:
 
 You know that the area of the smaller trapezoid is 771 m², then you can set up the following proportion, where "x" is the area of the larger trapezoid. Then you have:
 
 Now you must solve for "x". Therefore, you get that the area of the larger trapezoid is:
  
 
        
             
        
        
        
Answer:
x = 10 , -12
Step-by-step explanation:
Solution:-
- The given quadratic equation is to be solved using the quadratic formula. The general form of a quadratic equation is:
                             
  
Where, [ a , b and c are constants ]
- The quadratic formula is given as:
                         
                            
- The given equation is:
                              
Where, a = 1 , b = 2 , c = -120
- Solve using quadratic formula:
