Maximum Area of a Rectangle with Perimeter 100

Step 1. Let the two sides be x and y
Step 2. x+y+x+y=100
Step 3. y = 50-x
Step 4. Area = xy = x(50-x)
Step 5. Find the x-coordinate of the vertex
Step 6. Use that to find the max area (625 units^2)

So in the end if you get x and y to be 25 is the shape not going to be a square?

Why X can be zero and 50 cuz A is unknown yet and A can’t be zero, sorry I am abit confused
