(It also depends the shape of the figure the equation changes like this : b×B ² or P×A or other things)
Im not a 5th grader Im a 1st grader of secundary (Idk how its called in english i think its secondary)
I meant a easy equation there L=lado(spanish) Lado = side Side×4= L+L+L+L L+L+L+L = The resault changes but the equation does not If a square is 16×4L = 16+16+16+16 16+16+16+16 = 64 Wich means L+L+L+L=64 OR 16×4L=64
My brain makes it all complicated
