Answer:
Step-by-step explanation:
1) ABCD is a trapezium. AB ║ CD
∠ADC + ∠DAB  = 180°  { Co interior angles}
110° + ∠DAB = 180
          ∠DAB = 180 -110
∠DAB = 70°
2) Sum of all angles of trapezium = 360°
∠A + ∠B + ∠DCB + ∠D = 360
70° + 50° + ∠DCB + 110° = 360
                  230 + ∠DCB = 360
                             ∠DCB = 360 - 230
 ∠DCB = 130°
3) For finding the height, use Pythagorean theorem
 height² + base² = hypotenuse²
       height² + 6² = 10²
       height² + 36 =100
                height² = 100 - 36
               height² = 64
                height = √64
height = 8 m
4) a = AB = x m
   b = 9 m
h = height = 8 m
Area of trapezium = 120 m²
  = 120
  = 120

x + 9 = 120/4
x + 9 = 30
     x = 30 - 9
x = 21 m
AB = 21m
                               
 
        
             
        
        
        
The answer is strong negative. Hope this helps
