Question

Proof the perimeter of square is 4*side.?

Answer 1

The sum of the distance of all the lengths of the sides of an object. And in square all sides are equal.... Let call it of length 'a'. So a+a+a+a=4a

Answer 2

Let the side of the square be 'a'
we know that, all sides of square are equal,
Perimeter of square = a + a + a + a
                                 = 4a
                                 = 4*side
Therefore, perimeter of square is 4*side
