Question

if a square has side x then what will be its perimeter on doubling the side​

Answer 1

Answer:

doubling the side the perimeter will be 8x unit

Step-by-step explanation:

doubling the side , the length of each side if the square will be 2x unit

then the perimeter of the square be 4 × 2x unit = 8x unit

Answer 2

The side of the square is given to be x

So, initial perimeter of square = 4 × side

                                                  = 4x

Now, it is given that the side is doubled

So, new side = 2 × initial side

                      = 2x

New perimeter = 4 × side

                         = 4 × (2x)

                         = 8x

                         = 2 × initial perimeter

Hence, the perimeter on doubling the side will be 8x which is double the initial perimeter
