Answer: 80
Step-by-step explanation:
We can use the formula
, where
are the lengths of the diagonals.
By the distance formula,
![AC=\sqrt{(-2-2)^{2}+(-1-7)^{2}}=\sqrt{16+64}=4\sqrt{5}\\BD=\sqrt{(-8-8)^{2}+(-1-7)^{2}}=\sqrt{256+64}=8\sqrt{5}](https://tex.z-dn.net/?f=AC%3D%5Csqrt%7B%28-2-2%29%5E%7B2%7D%2B%28-1-7%29%5E%7B2%7D%7D%3D%5Csqrt%7B16%2B64%7D%3D4%5Csqrt%7B5%7D%5C%5CBD%3D%5Csqrt%7B%28-8-8%29%5E%7B2%7D%2B%28-1-7%29%5E%7B2%7D%7D%3D%5Csqrt%7B256%2B64%7D%3D8%5Csqrt%7B5%7D)
So, the area is ![\frac{(4\sqrt{5})(8\sqrt{5})}{2}=\boxed{80}](https://tex.z-dn.net/?f=%5Cfrac%7B%284%5Csqrt%7B5%7D%29%288%5Csqrt%7B5%7D%29%7D%7B2%7D%3D%5Cboxed%7B80%7D)

Answer:
This is simple,
Step-by-step explanation:
If the bus costs 200$ and the fair charges 4$ per students that means you have to do this:
300$ budget - 200 of the bus = 100$ left
and if $4 per student:
100 divided by 4 = 25
she can take 25 students
Hope this helps!
