Question

Периметр квадрата равен 27,2 см . Найдите его площадь . Ответ округлите до десятых

Answer 1

Так как у квадрата все стороны одинаковы (Р=а*4) то получаем:

1) 27,2:4 = 6,8

P квад.= a*a :

2) 6,8*6,8=46,24

так как 4 меньше 5, то она НЕ прибавляет единцы и мы получаем число равное 46,2

Answer 2

1) 27,2:4=6,8
2)6,8^2=46,2

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. Given that the perimeter of the square is 27.2 cm, we can calculate the length of each side by dividing the perimeter by 4, since a square has four equal sides.

Let's calculate the length of each side:

Perimeter of the square = 27.2 cm Length of each side = Perimeter / 4 = 27.2 cm / 4 = 6.8 cm

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

Area = side length * side length

Substituting the value of the side length, we get:

Area = 6.8 cm * 6.8 cm = 46.24 cm²

Therefore, the area of the square is 46.24 cm² when rounded to the nearest tenth.
