The question is related to application of derivatives .
Let A represents the area and s represent the side length .
Differentiating both sides with respect to t
It is given that ds/dt = 4cm/s
Substituting the values of s, ds/dt and on multiplying them, we will get
dA/dt = 2(5)(4) = 40 cm^2/s
Therefore rate of change of area when area= and rate of change of side is 4 cm/s is 40
