Question

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

Answer 1

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

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
