The answer to this very simple question is B:)
The original area of the rectangle is 
<u>Explanation:</u>
width = x
length = x + 2
area of the rectangle = x (x+2)
length = x + 2 + 5 = x+7

Solving this equation, we get
x =5ft
So, original width = 5ft
original length = 5+2ft = 7ft
Thus, original area of the rectangle = 5 X 7ft = 
Therefore, the original area of the rectangle is
