Our equation for the area of a rectangle is l x w = A (length times width equals area)
We know that l=w+20 so we can plug this into our equation.
It is now, (w+20) x w =800
We can then solve for w
w^2 +20w =800
We can subtract 800 on each side to get
w^2 +20w - 800 =0
We then factor to get
(w-20)(w+40)=0
This gives us w =20 and w = -40
Width cannot be negative so our width will be 20 feet
Since our length is 20 more than this, then our length will be 40feet
So the dimensions of the rectangle are 20 ft wide by 40 ft long

Answer:
56,161
Step-by-step Thought Process:
Use the equation: 
to solve this problem. Let x= time in years, a= initial amount, and r= growth rate.
= 
When you solve you get this number:
56,160.57516085
Round to the nearest whole number:
56,161
37/11 is correct just multiply 3*11 and add four
What you can do is count all the shapes the put the number of blue with that into a fraction. Lets say that there are 24 shapes and 15 are blue the fraction would be 15/25
