Hi!
The answer to this equation is
![\frac{1}{16}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B16%7D%20)
and the equation would look like this
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
÷ 8 =
Answer:
The rate of change of area is 35360 m /year
Step-by-step explanation:
Let the width of rectangle be w
We are given that a rectangle that is twice as long as it is wide
So, Length of Rectangle = 2w
Area of rectangle A = Length \times Breadth = ![w \times 2w= 2w^2](https://tex.z-dn.net/?f=w%20%5Ctimes%202w%3D%202w%5E2)
Differentiating area with respect to time
![A=2w^2\\\frac{dA}{dt}=4w\frac{dw}{dt}](https://tex.z-dn.net/?f=A%3D2w%5E2%5C%5C%5Cfrac%7BdA%7D%7Bdt%7D%3D4w%5Cfrac%7Bdw%7D%7Bdt%7D)
We are given that
and w = 260
![\frac{dA}{dt}=4(260)(34)=35360](https://tex.z-dn.net/?f=%5Cfrac%7BdA%7D%7Bdt%7D%3D4%28260%29%2834%29%3D35360)
Hence the rate of change of area is 35360
