The answer will depend on what kind of shape it is.
If an equilateral triangle and a square have equal perimeters, then the ratio of the area of the triangle to the area of the square is 1:3.

Yes, two rectangles can have the same area but different perimeters. The area of a rectangle is calculated by multiplying its length and width, while the perimeter is calculated by adding twice the length and twice the width. For example, a rectangle with dimensions 2x6 has an area of 12 and a perimeter of 16, while a rectangle with dimensions 3x4 also has an area of 12 but a perimeter of 14.
"18 perimeters" is is a meaningless phrase since there are no units of measurement. It is like asking how tall are 18 heights?
Because the area is different than the perimeters

Because the area is different than the perimeters
AxXY/Pi
they are different because perimeter is the out side of the shape and area is inside of the shape.

That depends on the rectangle! You can have different rectangles with the same area, but with different perimeters.
There is no perimeter of a circle. Only flat shapes have perimeters. You can however, find the circumference, surface area, and volume.
