 получается, что от каждого прямоугольника мы берем половину его периметра, это будет сумма двух его сторон, которые составляют периметр всего листа.
 Надеюсь понятно объяснила))))))

Answer 2

Calculation of the Perimeter of the Paper Sheet

To calculate the perimeter of the rectangular paper sheet, we need to find the lengths of its sides. The problem states that the sheet is divided into four rectangles, and the perimeters of these rectangles are given as 5 cm, 6 cm, 7 cm, and 8 cm.

Let's assume the lengths of the sides of the rectangles are a and b. We can set up the following equations based on the given information:

Equation 1: 2a + 2b = 5 cm Equation 2: 2a + 2b = 6 cm Equation 3: 2a + 2b = 7 cm Equation 4: 2a + 2b = 8 cm

To solve these equations, we can subtract Equation 1 from Equation 2, Equation 3, and Equation 4 successively. This will eliminate the variables a and b, leaving us with a single equation to solve.

Subtracting Equation 1 from Equation 2: (2a + 2b) - (2a + 2b) = 6 cm - 5 cm 0 = 1 cm

Subtracting Equation 1 from Equation 3: (2a + 2b) - (2a + 2b) = 7 cm - 5 cm 0 = 2 cm

Subtracting Equation 1 from Equation 4: (2a + 2b) - (2a + 2b) = 8 cm - 5 cm 0 = 3 cm

From these calculations, we can see that the equations are inconsistent. There is no solution that satisfies all four equations simultaneously. Therefore, it is not possible to determine the lengths of the sides of the rectangles and calculate the perimeter of the paper sheet based on the given information.
