Question

how much does shamim have to walk to go around a square field 10m​

Answer 1

She would have to walk 40 meters.

If side of a square is 10m then she had to go through 4 sides of equal length. Moreover, Distance covered by Her would be equal to the perimeter of the square.

And,

Perimeter =4(length of one side of square)

So, perimeter =4(10)=40m

Answer 2

Since Shamim has to walk around the field. So,

Distance Shamim has to walk = Perimeter of the square field

                                                  = 4 x (length of side of square)

                                                  = 4 x 10 m

                                                  = 40 m
