Given quadratic equation : 
Let us apply standard quadratic form 
We know, quadratic formula

a = 4
b = 2
c= -1
Now we plug in all the values in quadratic formula
.
<h3>The above one is the substitution of values of a,b,c in quadratic formula.</h3>
The perimeter is the length of the outside of an object. So for just one of those squares it would be 4. Or a 2x2 would be 8.
In this case you have 20 squares. Five of which two sides are exposed. All you need to do is count the outside lines
Your answer is 21ft.
