Today it is difficult to imagine a person who does not know how to count and manipulate in the mind with simple addition and subtraction. Mathematics is tightly embedded in all areas of our daily life. We count money, objects, time, etc. We begin to study mathematics at school. With each class, mathematics is becoming more complex and interesting.
However, not every child can know and understand some concepts. For example, many children are faced with the question of what the perimeter is and what the perimeter of the square is.Consider these questions in more detail.
A square is a regular quadrangle in which all sides are equal and form four right angles. The perimeter of the square, like that of the other figure, is the sum of all the lengths of its sides. Unlike other figures, it is easy enough to find the perimeter of a square due to its simple properties:
- All sides are equal. That is, the length is equal to the width of the square. This makes finding the perimeter easier;
- The sides of the square form four right angles (90 degrees each);
- The area of a square is the multiplication of length by width. Since the length and width are equal, the length of the side of the square is multiplied by itself.
Consider a few tasks on finding the perimeter of the square.
Options for finding the perimeter
In problems, there are often two options - one side of the square is given or the area of the square is given. Based on these data, you must find the perimeter:
- If the length of one of the sides of the square is given, then it must be multiplied by four, because the square has four sides and they are equal to each other.
- If a square is given, you must first find the side of the square. The square of the square is found through the multiplication of length by the width of the square, however, the sides are equal, and the formula can simply be represented as a side multiplication by itself, or you can square the length of the side of the figure. Therefore, to find the length of the side, you need to extract the root from the square of the square. Then the resulting number is simply multiplied by four and we get the perimeter of the square.
