Because 'perimeter' is a length, and area is an area.

Perimeter is the distance around the edges of a sheet of paper, while

area is the part of a table-top that the sheet of paper can cover.

You can never say how many square feet tall you are, and you can never say

how many feet your front yard covers. That would be swapping the units of

length and area, and using each unit for the wrong type of quantity.

What is the perimeter of 575 square units?

You can't tell. The area doesn't tell you the dimensions. There are an infinite number of different shapes with different dimensions and different perimeters that all have the same area. -- If the 575 square units of area are in the shape of a circle, then the radius of the circle is 13.53 units and the perimeter (circumference) is 85 units. (rounded) -- If the 575 square units of area are in the shape of a square, then each side of the square is 23.98 units and the perimeter is 95.92 units. (rounded) -- The 575 square units of area could also be a (23 x 25) rectangle, with perimeter of 96. -- The 575 square units of area could also be a (115 x 5) rectangle, with perimeter of 240. -- The 575 square units of area could also be a (575 x 1) rectangle, with perimeter of 1,152.

How do you find the area if the perimeter is only given?

If you are talking about a rectangle, you can't find the area from just the perimeter. With a perimeter of say 80 units, the sides could be 10 and 30, with an area of 300 square units. But the sides could also be 5 and 35, with an area of 175 square units. There are lots of other possibilities. If you are talking about a square, that's different. Each side is a quarter of the perimeter, so the area is a quarter of the perimeter multiplied by a quarter of the perimeter.
