Jackson's paintbrush makes a narrow strip with a width of 6.5 millimeters. Jackson has enough paint to make a strip 25 meters long. How many square centimeters of paper could Jackson cover with paint?

$\textbf{(A) }162.5\qquad\textbf{(B) }1,625\qquad\textbf{(C) }16,250\qquad\textbf{(D) }162,500\qquad\textbf{(E) }1,625,000$

Solution

$6.5$ mm = $0.65$ cm $25$ m = $2500$ cm $0.65\times2500=$=\boxed{\textbf{(B) }1,625}.$
