A: 184
1.) find the area of the two sides (length*height)*2
5*8=40*2=80
2.) Find the area of the adjacent sides (Width*height)*2
5*4=20*2=40
3.) Find the area of the ends (length*width)*2
4*8 =32*2=64
4.) add the three areas together
40+80+64=184

Answer: -1/2
Step-by-step explanation:
The average rate of change is
. Since a=-1 and b=1. We can plug them into the equation and solve.
![\frac{[1^2-1-1][(-1)^2-(-1)-1)]}{1-(-1)} =\frac{(-1)(1)}{2} =-\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B1%5E2-1-1%5D%5B%28-1%29%5E2-%28-1%29-1%29%5D%7D%7B1-%28-1%29%7D%20%3D%5Cfrac%7B%28-1%29%281%29%7D%7B2%7D%20%3D-%5Cfrac%7B1%7D%7B2%7D)
