1950 AHSME Problem 46

In triangle ABC, AB=12, AC=7, and BC=10. If sides AB and AC are doubled while BC remains the same, then:

\begin{array}{l} \textbf{(A)}\ \text{The area is doubled}\qquad\\ \textbf{(B)}\ \text{The altitude is doubled}\qquad\\ \textbf{(C)}\ \text{The area is four times the original area}\qquad\\ \textbf{(D)}\ \text{The median is unchanged}\qquad\\ \textbf{(E)}\ \text{The area of the triangle is 0} \end{array}
