I'm building a wall out of square blocks (1 ft x 1 ft) and want the wall to be perfectly square. Currently the unfinished wall has a width of 50 feet and an area of 2000 square feet. How many more blocks do I need to add to make the wall a perfect square with the present width? Select the correct option
A) 200
B) 10
C) 50
D) 500
E) 150
If the wall has a width of 50 and an area of 2000, then the current height is  2000/50= 
<gadget id="calculator"> 2000/50</gadget>
<output>40</output>
40   We must expand the height to 50 feet by adding 10 more rows.   Each row has a width of 50, so 500 more blocks are required to finish the wall.   The answer is 500.
