Question 15
Right triangles $T_1$ and $T_2$ have areas $1$ and $2$, respectively. A side of $T_1$ is congruent to a side of $T_2,$ and a different side of $T_1$ is congruent to a different side of $T_2.$ What is the square of the product of the lengths of the other (third) sides of $T_1$ and $T_2?$
