Homework Statement
Question: the base b and height h change with a time t in such a way that b= [tex](t+1)^{2}[/tex] and h= [tex]t^{2}+1[/tex]
Determine the rate of change of the area of the triangle when t=3
Homework Equations
[tex]A=\frac {1}{2}(b)(h)[/tex]
The Attempt at a Solution
I am not sure what to do here.
Do you just multiply it out using the area of a triangle? Or should I take the derivative of both then use the area formula?
