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.

"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
they are different because perimeter is the out side of the shape and area is inside of the shape.

yes, for example:a 4 by 5 rectangle has an area of 20 and a perimeter of 18a 2 by 7 rectangle has an area of 14 and a perimeter of 18yes, for example:

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.
