Calculeaza perimetrul patratului stiind lungimea laturii lui. Exprima rezultatul in unitati de masura indicate A=54mm Raspuns: Ppartrat = ? Mm,? Cm,? Mm

perimeter = 2*a = 2*54 mm = 108 mm

Step-by-step explanation:

For any geometrical figure, the perimeter is the sum of all his sides.

In a rectangle figure, have four sides, two of them equals: a (upper side), b (lateral side), so the perimeter will be:

perimeter = a+a+b+b = 2 * (a+b)

A square is a particular case of rectangle figure, in which: a = b.

So, for a square:

perimeter = 2 * (a+a) = 2 * (2a) = 4*a
