Well think about it ....
1 yard = 3 ft so you'd do 3 times 4
1 foot = 12 inches so it'd be half of a foot
        
                    
             
        
        
        
Answer:
14.4 miles 
Step-by-step explanation:
Given that :
Distance moved North = 12 miles
Distance moved West = 8 miles
Shortest distance to reach starting point :
Let shortest distance to reach starting point = d miles
Using the relation :
Longest side of a right angled triangle:
d = sqrt(8^2 + 12^2)
d = sqrt(64 + 144)
d = sqrt(208)
d = 14.422205
d = 14.4 miles (nearest tenth of a mile) 
 
        
             
        
        
        
Answer:
<h3>
  The width (side perpedicular to the barn):  
<u>x = 8 m</u></h3><h3>      The lenght (side parallel to the barn):  
<u>y = 16 m</u> </h3>
Step-by-step explanation:
x  - the width of the barn
She has 32 m of fencing so for the lenght remain (32-2x) m of fencing:
y = 32 - 2x
Area of the fencing:  A = x•y
A(x) = x•(32 - 2x)
A(x) = -2x² + 32x             ←  quadratic function
The maximum value of quadratic function occurs at:  
a = -2,  b = 32

32-2x = 32 - 2•8 = 16
