Question

2 кв.м 7 кв. дм-20012 кв. см

Answer 1

1 м² = 100 дм² = 10 000 см²

2 м² 7 дм² - 20 012 см² = (20 000 + 700) см² - 20 012 см² =

20 700 см² - 20 012 см² = 688 см² = 6 дм² 88 см².

Ответ: 6 дм² 88 см².

Answer 2

To convert 2 square meters and 7 square decimeters into square centimeters, we need to add up the total area in square centimeters.

1 square meter is equal to 10,000 square centimeters, and 1 square decimeter is equal to 100 square centimeters.

So, first, we convert 2 square meters into square centimeters:

2 square meters = 2 x 10,000 = 20,000 square centimeters

Then, we convert 7 square decimeters into square centimeters:

7 square decimeters = 7 x 100 = 700 square centimeters

Finally, we add these two values together to get the total area in square centimeters:

20,000 square centimeters + 700 square centimeters = 20,700 square centimeters

Therefore, 2 square meters and 7 square decimeters is equal to 20,700 square centimeters.
