Answer:
Change in area=24
-48
Step-by-step explanation:
Let s will be the side of square and r will be the radius of circle.
Then two given conditions are
1)dr/dt=2 m/s
2)ds/dt=1 m/s
Area enclosed=(Area of square)-(Area of circle)
Area of square=![s^{2}](https://tex.z-dn.net/?f=s%5E%7B2%7D)
Area of circle=![\pi r^{2}](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D)
Area enclosed=![(\pi r^{2})-s^{2}](https://tex.z-dn.net/?f=%28%5Cpi%20%20r%5E%7B2%7D%29-s%5E%7B2%7D)
dA/dt=2
r(dr/dt)-2s(ds/dt)
At s=24,and r=6
dA/dt=2(
)(6)(2)-2(24)(1)
Change in area=24
-48
