GRE Math Practice: This GRE quantitative comparison question tests your understanding of percent changes and area of right triangles.
Question#72: In right triangle $ABC$, the length of the height is increased by $25\%$ and the length of the base is decreased by $25\%$ to create a new right triangle $DEF$.
$\begin{array}{c c c c c c}
& \underline{\textrm{Quantity A}} & & & & \underline{\textrm{Quantity B}} \\
& & & & & \\
& \textrm{Area of triangle $ABC$} & & & & \textrm{Area of triangle $DEF$}\\
\end{array}$
- $\quad \textrm{Quantity A is greater.}$
- $\quad \textrm{Quantity B is greater.}$
- $\quad \textrm{The two quantities are equal.}$
