Question

Вычисли периметр прямоугольника у которого сумма длин соседних сторон равна 4 сантиметра

Answer 1

P=2(a+b)
a+b=4
P= 2 × 4 = 8

Answer 2

Две стороны равны  в сумме 4, следует Р=4*2 =8см

Answer 3

Calculating the Perimeter of a Rectangle

To calculate the perimeter of a rectangle where the sum of the lengths of adjacent sides is equal to 4 centimeters, we can use the formula for the perimeter of a rectangle, which is P = 2(a + b), where a and b are the lengths of the adjacent sides.

Using the Given Information

The given information states that the sum of the lengths of adjacent sides is equal to 4 centimeters. We can use this information to calculate the perimeter of the rectangle.

Applying the Formula

We can apply the formula for the perimeter of a rectangle, P = 2(a + b), where a and b are the lengths of the adjacent sides. Since the sum of the lengths of adjacent sides is 4 centimeters, we can express one side as x and the other side as (4 - x).

Calculating the Perimeter

Substituting the values into the formula, we get: P = 2(x + (4 - x)) P = 2(4) P = 8 centimeters

So, the perimeter of the rectangle is 8 centimeters. This calculation is based on the given information and the formula for the perimeter of a rectangle.

I hope this helps! If you have any other questions, feel free to ask.

Answer 4

Периметр прямоугольника можно вычислить по формуле: P = 2*(a + b), где a и b - длины сторон прямоугольника.

Если сумма длин соседних сторон равна 4 см, то можно предположить, что одна сторона равна 2 см, а другая также равна 2 см.

Тогда периметр прямоугольника будет равен: P = 2*(2 + 2) = 2*4 = 8 см.

Таким образом, периметр прямоугольника равен 8 сантиметрам.
