Answer: 
16.7 Units
Step-by-step explanation:
To find the length of r, you set up the equation as sin(45)= 4.9/r. Then you get r by itself changing it to r = 4.9/sin(45). Then you can find that r = 6.9. Since this is an isosceles triangle, n^1 has to be equal to 4.9. Then you add all the side lengths together. 4.9 + 4.9 + 6.9 = 16.7 units

<span>Perimeter =2w+2L= 520. 
We can solve this by understanding that the area is maximized by a square
Therefore L=w. 
p=2w+2w=520=4w
w=130 
Area
 
A=wL=130(130)= 16900 square yards</span>

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 2x
x = -y + 6
<u>Step 2: Solve for </u><em><u>y</u></em>
<em>Substitution</em>
- Substitute in <em>x</em>:                     y = 2(-y + 6)
- Distribute 2:                         y = -2y + 12
- Isolate <em>y</em> terms:                    3y = 12
- Isolate <em>y</em>:                               y = 4
<u>Step 3: Solve for </u><em><u>x</u></em>
- Define equation:                    x = -y + 6
- Substitute in <em>y</em>:                       x = -4 + 6
- Add:                                        x = 2
