Question

Периметр квадрата равен 56см. чему равна его площадь?

Answer 1

Периметр квадрата вычисляется по формуле:
Р=4а
Нам известен периметр, поэтому мы можем подставить его значение в эту формулу и найти длину стороны квадрата
56=4а
а=56/4
а=14
Теперь вычислим площадь квадрата по формуле
S=a^2
S=14^2=196
Вот и ответ

Answer 2

56\4=14
14*14*14*14=196

Answer 3

Perimeter and Area of a Square

To find the area of a square, we first need to determine the length of its sides. In this case, we know that the perimeter of the square is 56 cm. The perimeter of a square is the sum of all its sides.

Let's denote the length of one side of the square as a. Since a square has four equal sides, the perimeter can be calculated as:

Perimeter = 4a

Given that the perimeter is 56 cm, we can set up the equation:

4a = 56

To find the length of one side, we divide both sides of the equation by 4:

a = 56 / 4 = 14 cm

Now that we know the length of one side, we can calculate the area of the square. The area of a square is given by:

Area = side^2

Substituting the value of the side length, we have:

Area = 14^2 = 196 cm^2

Therefore, the area of the square is 196 square centimeters.
