Find the Greatest Common Factor (GCF)
GCF = 3
Factor out the GCF. (Write the GCF first, and then in parenthesis, divide each term by the GCF)
3(3x/3 + 18/3)
Simplify each term in parenthesis 
<u>= 3(x + 6)</u>

h/10 + 2h/10
= 1290
3h/10 = 1290
3h = 12,900
h = 4300
 
        
                    
             
        
        
        
area of floor = length * width
length =18 feet
width =12 feet
area =12*18 = 216 feet square
