Question

Анара делает аппликацию на уроке труда . Сколько квадратов со стороной 3 см (5см) она сможет вырезать из листа цветной бумаги, имеющей длину 15 см и ширину 9 см?

Answer 1

Для квадрата со стороной 3 см
1) 9 : 3 = 3 квадрата по ширине
2) 15 : 3 = 5 квадратов по длине
3) 5 * 3 = 15 квадратов со стороной 3 см всего получится 

Для квадрата со стороной 5 см
1) 9 : 5 = 1 квадрат по ширине
2) 15 : 5 = 3 квадрата по длине
3) 3 * 1 = 3 квадрата со стороной 5 см всего получится 

Answer 2

Calculating the Number of Squares

Anara wants to make an application during her craft class. She wants to cut squares with a side length of 3 cm (5 cm) from a colored paper sheet that is 15 cm long and 9 cm wide. Let's calculate how many squares she can cut from the given paper sheet.

To calculate the number of squares Anara can cut, we need to consider the dimensions of the paper sheet and the side length of the squares.

The area of the paper sheet is 15 cm * 9 cm = 135 square cm.

For squares with a side length of 3 cm: The area of each square is 3 cm * 3 cm = 9 square cm. So, the number of squares Anara can cut with a side length of 3 cm is 135 square cm / 9 square cm = 15.

For squares with a side length of 5 cm: The area of each square is 5 cm * 5 cm = 25 square cm. So, the number of squares Anara can cut with a side length of 5 cm is 135 square cm / 25 square cm = 5.

Therefore, Anara can cut 15 squares with a side length of 3 cm and 5 squares with a side length of 5 cm from the given paper sheet.
