One diagonal of a rhombus is *decreasing* at a rate of $7$ centimeters per minute and the other diagonal of the rhombus is increasing at a rate of $10$ centimeters per minute. At a certain instant, the decreasing diagonal is $4$ centimeters and the increasing diagonal is $6$ centimeters. **What is the rate of change of the area of the rhombus at that instant (in square centimeters per minute)?** [[☃ radio 1]] *The area of a rhombus with diagonals $d_1$ and $d_2$ is $\dfrac{d_1d_2}{2}$.*
