У Иры 12 пакетиков семян однолетних цветов и 8 пакетиков семян многолетних цветов. Ира посадила семена из 9 пакетиков. сколько пакетиков с семенами осталось у Иры? периметр квадрата 12см. чему равна сторона квадрата. начерти этот квадрат

Answer 1

12+8=20(пакетиков семян) - всего
20-9=11(пакетиков семян) - осталось у Иры
Ответ: 11

Answer 2

Calculating Remaining Seed Packets

To calculate the number of seed packets remaining for Ira, we can start by adding the total number of seed packets she had and then subtracting the number of packets she used.

Ira had: - 12 packets of annual flower seeds - 8 packets of perennial flower seeds

She used seeds from 9 packets.

So, the total number of seed packets Ira had was 12 + 8 = 20.

After planting seeds from 9 packets, the number of seed packets remaining is 20 - 9 = 11.

Finding the Side Length of the Square

To find the side length of the square with a perimeter of 12 cm, we can use the formula for the perimeter of a square, which is 4 times the length of one side.

The formula for the perimeter of a square is: Perimeter = 4 * side length

Given that the perimeter is 12 cm, we can solve for the side length: 12 = 4 * side length

Dividing both sides by 4 gives us: side length = 12 / 4 = 3 cm

Drawing the Square

To draw the square, we can simply create a square with all four sides measuring 3 cm each. Here's a representation of the square:
