Lets first convert everything to inches.
6 feet= 12*6 = 72 + 10 = 82 inches
8 feet= 12*8 = 96+9 =  105 inches
Now add!
82+105 = 187
Now convert them back to feet.
187/12 = 15 feet
12*15 = 180
187 - 180 = 7 inches
15 feet. 7 inches. 
Final answer: B. 15 ft. 7 in.
        
                    
             
        
        
        
From the information provided by the statement, you know that
 *Ann draws 2/16 of the playground
 *Susan draws 6/16 of the playground because she draws 3 times as much as Ann so

 *Louise draws 3/16 because she draws half as much as Susan, so

 *Sam draws 2/16 because she draws 1 less section than Louise

Now, let x be the fraction of the playground that still needs to be drawn. Then, you have

Therefore, 3/16 of the playground still needs to be drawn.
