Hello :
4√2-7√2= (4-7)√2 = -3√2 
        
             
        
        
        
Hi there! 
The formula for the area of a triangle is A = 1/2(b x h). Using the information provided, all we have to do is plug in what we know and solve! 
WORK: 
74 = 1/2(b x 9.14)
148 = b x 9.14 
b = 16.2 inches (approximately)
Hope this helps!! :)
