Need help with the question at the top<br><br> Thanks

First we must find area of a single square.

Meaning we divide total area of 80 centimetres squared by 5 since we have 5 squares in the shape.

$A_{square}=\frac{A_{shape}}{5}=\underline{16}$

Now from the picture we can see that the perimeter of shape is combined by 4 times 3 times the length of side of 1 square.

So we need to find side of 1 square.

$a=\sqrt{A_{square}}=\sqrt{16}=\underline{4}$

As we stated before the formula for perimeter of this shape is:

$P=4(3\cdot a)=4(3\cdot4)=4\cdot12=\boxed{48}$

The perimeter of shape is 48 centimetres.

Hope this helps.

Answer:

$\large \boxed{\textbf{30.54 yr}}$

Step-by-step explanation:

For species A,

$P =2000e^{0.05t}$

For species B,

$P =5000e^{0.02t}$

When their populations are equal,

$\begin{array}{rcl}2000e^{0.05t} & = & 5000e^{0.02t}\\e^{0.05t} & = & 2.5e^{0.02t}\\0.05t & = & \ln2.5 + 0.02t\\0.05t & = & 0.9163 + 0.02t\\0.03t & = & 0.9163\\t& = & \dfrac{0.9163}{0.03}\\\\& = & \mathbf{30.54}\\\end{array}\\\text{The populations of species A and B will be the same in $\large \boxed{\textbf{30.54 yr}}$}$

The diagram below shows the population of Species A overtaking that of Species B in about 30.5 yr.
