$(1$ point$)$ The altitude $($i$.$e$.,$ height$)$ of a triangle is increasing at a rate of $3\mathrm{.}5c\frac{m}{?}$ minute while the area of the triangle is increasing at a rate of $3\mathrm{.}5$ square $c\frac{m}{m}i$

$ute.$ At what rate is the base of the triangle changing when the altitude is $9\mathrm{.}5$ centimeters and the area is $89$ square centimeters?

The base is changing at $c\frac{m}{m}in.$
