Question

Длина стороны квадрата равна 15 см. запиши выражение для вычисления периметра этого квадрата

Answer 1

15*4=420 см. Если cторона квадрата это X , то X*4=Pкв

Answer 2

Периметр квадрата = a*4
P=a*4
P=15*4=60 см

Answer 3

Perimeter of a Square

To calculate the perimeter of a square, you need to add up the lengths of all four sides. In this case, the length of each side of the square is given as 15 cm.

The formula for calculating the perimeter of a square is:

Perimeter = 4 * side length

Substituting the given side length of 15 cm into the formula, we get:

Perimeter = 4 * 15 cm

Simplifying the expression, we find:

Perimeter = 60 cm

Therefore, the perimeter of the square with a side length of 15 cm is 60 cm
