Question

Найди площадь каждого участка земли и скажи сколько пакетов с семенами травы надо купить, чтобы засеять эти участки. На каждые 10 кв см нужен 1 пакет 1 участок 4 кв см 2 участок 12 кв см 3 участок 6 кв см

Answer 1

Определить кол-во пакетов по пропорции: 1. 4×1÷10=0,4. 2. 12×1÷10=1,2. 3. 6×1÷10=0,6.

Answer 2

Calculating Land Area and Grass Seed Packets

To calculate the area of each land plot and determine the number of grass seed packets needed to cover them, we can use the following information:

1. Land Plot Areas: - Plot 1: 4 sq cm - Plot 2: 12 sq cm - Plot 3: 6 sq cm

2. Grass Seed Packet Requirement: - 1 packet is needed for every 10 sq cm of land.

Calculating Land Plot Areas

To calculate the total area of each land plot, we can simply add up the individual areas:

- Plot 1: 4 sq cm - Plot 2: 12 sq cm - Plot 3: 6 sq cm

Determining Grass Seed Packet Requirement

To determine the number of grass seed packets needed for each plot, we can use the given requirement of 1 packet for every 10 sq cm of land.

1. Plot 1: - Area: 4 sq cm - Grass Seed Packets Needed: 1 packet (as the area is less than 10 sq cm)

2. Plot 2: - Area: 12 sq cm - Grass Seed Packets Needed: 2 packets (as the area is greater than 10 sq cm)

3. Plot 3: - Area: 6 sq cm - Grass Seed Packets Needed: 1 packet (as the area is less than 10 sq cm)

Therefore, to cover the three land plots, a total of 4 grass seed packets are needed.
