Opposite angles are equal to each other
 
        
             
        
        
        
Assume that 100% = 45 sales and 35% = X sales amount
You can create a ratio to help you solve for x 
45 = 100%
x   =  35 %
Which is equal to this fraction:  (45/x) = (100/35)
Solving for X by cross multiplying and dividing by 100: 
  [(45)(35)] / 100  =  X = 15.75 = 16 sales (rounded up)
You would need at least 16 sales to increase sales total by 35%

Answer:
11) 49 in.²
13) 4.515 m²
Step-by-step explanation:
11) area of square = (side)²
area = (7 in.)² = 7 in. × 7 in. = 49 in.²
13) area of triangle = base × height/2
area = 4.3 m × 2.1 m / 2 = 4.515 m²
