We know area of triangle = 
In triangle ABC , AB is the base and BC is the height
Now we find the distance between A and B
Distance formula is 
A(0,3), B(7,3)
Distance AB = 
=  = 7
 = 7
 B(7,3), C(7,7)
Distance BC = 
=  = 4
 = 4
area of triangle = 
area of triangle = 
=  = 14
 = 14 
 
        
             
        
        
        
Answer:
$8.1
Step-by-step explanation:
Convert 45 yards of ribbon to feet through proper conversion factor.  
   (45 yards)(3 ft / 1 yard) = 135 feet
Divide this number by 5 to determine the number of 5-ft ribbon that customers can purchased.
     n = 135 ft / 5 ft = 27
Then, multiply by $0.80.
    R = (27)($0.80) = $21.6
The profit is equal to $21.6 and $13.50,
     P = $21.6 - $13.50 = $8.1
