Question

А)в квадратные сантиметры 17дм.2=3м.2 2дм.2=40м.2=б)в квадратные метры 50700дм.2=100000см.2=340000см.2=

Answer 1

17 дм²= 1700 см²
3 м² 2 дм²= 302 дм²= 30200 см²
40 м²= 400000 см²
50700 дм²= 507 м²
100000 см²= 10 м²
340000 см²= 34 м²

Answer 2

To convert the given areas to square centimeters and square meters, we need to use the following conversion factors:

1 square decimeter (dm^2) = 100 square centimeters (cm^2) 1 square meter (m^2) = 10,000 square centimeters (cm^2)

Let's perform the conversions step by step:

А) Converting to square centimeters:

1. 17 dm^2 to cm^2: 17 dm^2 * 100 cm^2/dm^2 = 1,700 cm^2

2. 3 m^2 2 dm^2 to cm^2: 3 m^2 * 10,000 cm^2/m^2 + 2 dm^2 * 100 cm^2/dm^2 = 30,000 cm^2 + 200 cm^2 = 30,200 cm^2

3. 2 dm^2 to cm^2: 2 dm^2 * 100 cm^2/dm^2 = 200 cm^2

Б) Converting to square meters:

1. 50,700 dm^2 to cm^2: 50,700 dm^2 * 100 cm^2/dm^2 = 5,070,000 cm^2

2. 100,000 cm^2 to m^2: 100,000 cm^2 / 10,000 cm^2/m^2 = 10 m^2

3. 340,000 cm^2 to m^2: 340,000 cm^2 / 10,000 cm^2/m^2 = 34 m^2

So, the conversions are as follows:

А)

1. 17 dm^2 = 1,700 cm^2
2. 3 m^2 2 dm^2 = 30,200 cm^2
3. 2 dm^2 = 200 cm^2

Б)

1. 50,700 dm^2 = 5,070,000 cm^2
2. 100,000 cm^2 = 10 m^2
3. 340,000 cm^2 = 34 m^2
