Problem 2

A square with side length 8 is cut in half, creating two congruent rectangles. What are the dimensions of one of these rectangles?

$\textbf{(A)}\ \emph{2\ by\ 4}\qquad\textbf{(B)}\ \emph{\ 2\ by\ 6}\qquad\textbf{(C)}\ \emph{\ 2\ by\ 8}\qquad\textbf{(D)}\ \emph{4\ by\ 4}\qquad\textbf{(E)}\ \emph{4\ by\ 8}$

Solution

Cutting the square in half will bisect one pair of sides while the other side will remain unchanged. Thus, the new square is $\frac{8}{2}*8$ , or $\qquad\textbf{(E)}\ 4*8$ .
