<span>The answer is:
1.625.</span>
Answer:
1/4, 1/8, 1/16
i don't know this is my guess but these are small and close to zero
The third one is a point with the first equation.
I had to simplify the second equation.
It simplified to,

The second one with the above is didn't go through so I'd say no solution.
Answer: 500,000
Step-by-step explanation:
For 1.
Solution,
Sides(l)= 3.5
Now,
Perimeter of square=4l
=4*3.5
=14
Then,
Area of square =l^2
=3.5*3.5
=12.25
For 2.
Solution,
Sides(l)=1
Now, perimeter of square =4l
=4*1
=4
Then,
Area of square =l^2
=1*1
=1
For 3.
Solution,
Sides(l)= 20
Now,
Perimeter of square=4l
=4*20
=80
Then,
Area of square =l^2
=20*20
=400
