Question

Катя сложила из палочек прямоугольник длина которого 25 сантиметров а ширина 10 сантиметров сколько палочек использовала катя если длина одной палочки 55 миллиметров

Answer 1

25см=250мм
10см=100мм
250+250+100+100=700(мм)- периметр прямоугольника.
700:55=12,72727272727273(шт.)-палочек

Answer 2

Calculation of the Number of Sticks Used by Katya

To calculate the number of sticks used by Katya to form a rectangle, we need to determine the number of sticks required for both the length and width of the rectangle.

Given: - Length of the rectangle: 25 centimeters - Width of the rectangle: 10 centimeters - Length of one stick: 55 millimeters

To calculate the number of sticks for the length, we need to convert the length of the rectangle from centimeters to millimeters: - Length of the rectangle in millimeters: 25 centimeters * 10 millimeters/centimeter = 250 millimeters

Next, we divide the length of the rectangle in millimeters by the length of one stick to find the number of sticks required for the length: - Number of sticks for the length: 250 millimeters / 55 millimeters/stick = 4.545 sticks

Since we cannot have a fraction of a stick, we round up to the nearest whole number to ensure we have enough sticks to cover the length. Therefore, Katya would need 5 sticks for the length of the rectangle.

Similarly, we calculate the number of sticks for the width of the rectangle: - Number of sticks for the width: 10 centimeters * 10 millimeters/centimeter = 100 millimeters - Number of sticks for the width: 100 millimeters / 55 millimeters/stick = 1.818 sticks

Again, we round up to the nearest whole number, so Katya would need 2 sticks for the width of the rectangle.

Therefore, Katya would need a total of 5 + 2 = 7 sticks to form a rectangle with a length of 25 centimeters and a width of 10 centimeters, assuming the length of one stick is 55 millimeters.
