Answer: 7 times 4
Step-by-step explanation:
 
        
             
        
        
        
8/ Sine 50 = n/ Sine 90 
8 sine 90 = n Sine 50 
8 sine 90 / sine 50 = n 
n = 10.4 
        
             
        
        
        
The formula for the area of a trapezoid is A = a+b/2 * h. So just plug in the dimensions.
A = 5 + 3/2 * 5
A = 8/2 * 5
A = 4 * 5
A = 20 units²
