Notice that we can calculate the area of the square and the rectangle separately to get the following:

$\begin{gathered} A_1=3\cdot3=9in^2 \\ A_2=9\cdot2=18in^2 \\ \Rightarrow A=A_1+A_2=9+18=27in^2 \end{gathered}$

therefore, the total area is 27 in^2

A forest fire covers 1600 acres at time t=0. the fire is growing at a rate of 9\sqrt{t} acres per hour, where t is in hours. how

babymother [125]

To solve this problem you must apply the proccedure shown below:

1. You have that the forest fire covers 1600 acres at time t=0. the fire is growing at a rate of 9√t<span> acres per hour. Therefore, you have:
</span>
1600+∫(9√t)dt (from 0 to 16)

2. Then, when you solve it, you obtain:

1600+6t^3/2=1984

3. Therefore, as you can see, the answer is: 1984 acres.
