Question

Периметр аркуша паперу квадратної форми становить 36 см. Скільки смужок для закладок можна вирізати з цього аркуша , якщо ширина смужки 3 см

Answer 1

Ответ:

3

Пошаговое объяснение:

Периметр квадрата = 4 а

а = 9 см.

Площадь листа  равна 81 см2

Ширина закладки 3 см, тогда длина 9 см.

Площадь 1 закладки = 3*9 = 27 см2

81/27 = 3 закладки

Answer 2

Calculating the Number of Bookmarks Strips

To calculate the number of bookmark strips that can be cut from the square sheet of paper, we can use the following approach:

1. Calculate the Length of Each Side of the Square: - Since the perimeter of the square sheet is 36 cm, we can calculate the length of each side by dividing the perimeter by 4. - The length of each side of the square sheet is 36 cm / 4 = 9 cm.

2. Determine the Length of the Bookmark Strip: - The width of the bookmark strip is given as 3 cm.

3. Calculate the Number of Strips: - To find the number of strips that can be cut, we divide the length of each side of the square by the width of the strip. - Number of strips = (Length of each side of the square) / (Width of the strip) - Number of strips = 9 cm / 3 cm = 3 strips.

Therefore, 3 strips for bookmarks can be cut from this square sheet of paper.
