The area

S = a2

This means that in order to calculate

Example:

**of a square**is given by:S = a2

This means that in order to calculate

*the area***of a square**, multiply the lengths of two its sides on top of each other. As a result, if you know*the area***of a square**, when you root from this value is possible to know the length of a side**of the square**.Example:

*area***of a square is**36 cm2, to find the side of this**square**, you must take the square root of the area values. Thus, the side length of the**square**6 cm2

To find

P = a+a+a+a.

If you extract the square root of the area values

**the perimeter of**a**square**must add up the lengths of all its sides. Using the formula this can be expressed as:P = a+a+a+a.

If you extract the square root of the area values

**of the square**and then fold the resulting value 4 times, we can find**the perimeter****of a square**.3

Example: Given a square with

Solution:

You must first extract the square root

Then, by computing the length of a side

Answer:

*area*49 cm2 Yu. It is required to find its**perimeter**.Solution:

You must first extract the square root

**of the square**: √49 = 7 cmThen, by computing the length of a side

**of a square**, we can calculate**the perimeter**: 7+7+7+7 = 28 cmAnswer:

**the perimeter****of a square***area*u 49 cm2 is 28 cmNote

For square fair the following definitions:

A square is a rectangle that has equal sides.

A square is a special kind of rhombus, each of whose angles is equal to 90 degrees.

Being right in a square, around the square can be described or inscribed circle. The radius of the inscribed square in the circle can be found by the formula:

R = t/2, where t is the square side.

If the circle described around it, then its radius is:

R = (√2*t)/2

Based on these formulas, we can derive new to find the perimeter of a square:

P = 8*R, where R is the radius of the inscribed circle;

P = 4*√2*R, where R is the radius of the circumscribed circle.

The square is a unique geometric figure, since it is completely symmetrical, regardless of how and where to draw the axis of symmetry.
