Thought process: A square has 4 sides of equal length. If the perimeter (measurement around the outside) is 12 feet, that means each side is 3 feet.
The area is found by multiplying length by height. Length=3 feet, height=3 feet. Area is 9 square feet
Sometimes drawing a picture helps.

Perimeter P = sums of the lengths of the sides of the polygon
A square has four sides of equal length call the length s. So the perimeter is
P =s+s+s+s = 4s
The area is A =s*s = s^2 but s = P/4 so
A = s^2 = P^2/16 = 144/16 = 9 sq.ft.

A total of 12 feet? Or 12 feet on each? At 12 on each, it is 144 square feet. If it were 12 total, using the example of a rectangle measuring 1' x 5', the total would be 5 square feet.
You don't need all those complex ratios. It is a simple box, not a building site. Those guys are showing off. It is just plain common sense, a quality curiously lacking in some.

9 feet because 12/4 = 3 3x3=9

(12/4)^2 = 9 ft^2

Each side is 3 ft
A = 9 ft ²
