64га+82560000кв.мм+3900кв.дм=...а...кв.см?

Answer 1

Ответ:

Пошаговое объяснение:

64га= 640000000000 квадратных миллиметров

640000000000 кв.мм+82560000 кв.мм=640082560000 кв.мм

3900 кв.дм=39000000 кв. мм

640082560000 кв. мм+39000000 кв.мм=640121560000 кв.мм

640121560000 кв.мм=6401 а 215 см2 6 мм2

Answer 2

To add the given areas in different units, we need to convert them all to the same unit before performing the addition. Let's convert all the areas to square centimeters (cm²) since that's what the question is asking for.

1 hectare (га) = 10,000 square meters (м²) 1 square meter (м²) = 10,000 square centimeters (см²)

1 square decimeter (кв.дм) = 100 square centimeters (см²) 1 square millimeter (кв.мм) = 0.01 square centimeters (см²)

Now, let's convert each area to square centimeters:

64 га = 64 * 10,000 m² = 640,000 m² = 640,000 * 10,000 см² = 6,400,000,000 см² 82560000 кв.мм = 82560000 * 0.01 см² = 825,600 см² 3900 кв.дм = 3900 * 100 см² = 390,000 см²

Now, let's add all the areas in square centimeters:

6,400,000,000 см² + 825,600 см² + 390,000 см² = 6,401,215,600 см²

So, the sum of 64 га, 82560000 кв.мм, and 3900 кв.дм is 6,401,215,600 square centimeters (см²).
