Question

Perimeter of the square, whose each side is 'n' cm is: (a) n + 4 (b) 4n (c) n - 4 (d) ^ (n/2)​

Answer 1

Answer:

Perimeter of the square, whose each side is 'n' cm is: (b) 4n

Step-by-step explanation:

The perimeter of the square is defined as the sum of  length of the boundary of a square. We need to add all the sides of square to find its perimeter.

By the formula of perimeter of polygon, we know;

Perimeter = sum of all sides

Perimeter of square = Sum of the lengths of 4 sides

                = side + side + side + side

             = 4 × side

Therefore, the perimeter of Square = 4n units

Where, n = Length of a side of the square

Answer 2

b) 4n is the answer. The perimeter of a square is sum of all the sides. The sides are equal to n, therefore the sum is n+n+n+n, which is equal to 4n.
