How to find the length of the side of a square with a perimeter of 12 cm and how to draw a given square and calculate its area?

All four sides of the square are the same size, that is, they are all the same. Recall that the perimeter is the sum of all four sides of a given figure. Therefore, in order to subtract 1 side, it is necessary to divide the perimeter by the number of all sides:

12 cm / 4 sides = 3 cm – each side becomes.

That is, both the length and the width of the square are 3 cm.

Hence, it is necessary to draw a square, all sides of which = 3 cm.

Now let’s subtract the area by multiplying the length by the width:

S = 3 cm * 3 cm = 9 cm2.
