Mr. Green  measures his rectangular garden by walking two of the sides and finding that it is <math>15</math> steps by <math>20</math> steps.  Each of Mr. Green's steps is <math>2</math> feet long.  Mr. Green expects a half a pound of potatoes per square foot from his garden.  How many pounds of potatoes does Mr. Green expect from his garden?
 
 
 
<math> \textbf{(A)}\ 600 \qquad\textbf{(B)}\ 800  \qquad\textbf{(C)}\ 1000 \qquad\textbf{(D)}\ 1200 \qquad\textbf{(E)}\ 1400 </math>
 
 
 
==Solution==
 
 
 
Since each step is <math>2</math> feet, his garden is <math>30</math> by <math>40</math> feet.  Thus, the area of <math>30(40) = 1200</math> square feet.  Since he is expecting <math>\frac{1}{2}</math> of a pound per square foot, the total amount of potatoes expected is <math>1200 \times \frac{1}{2} =  \boxed{\textbf{(A) }600}</math>
