Question

4428400см2 - 25м2 - 482 дм2 = 2563400см2 - 32м2 - 12дм2 =

Answer 1

1)

4428400 см2 =  442,84 м2

482 дм2 = 4.82 м2

442,84-25-4,82=413,02м2

2)

2563400 см2 =  256,34 м2

12 дм2 = 0,12 м2

256,34-32-0,12= 224,22 м2

Answer 2

Let's simplify the expressions on both sides:

1. First expression: 4428400 см² - 25 м² - 482 дм² To perform this calculation, we need to convert all units to the same unit (either square centimeters or square meters). Let's convert everything to square centimeters:

   • 25 m² = 25 * 10,000 cm² (1 m = 100 cm)
   • 482 дм² = 482 * 100 cm² (1 дм = 10 cm)

   Now, we can calculate the first expression:

   4428400 см² - 25 * 10,000 cm² - 482 * 100 cm² = 4428400 см² - 250,000 cm² - 48,200 cm² = 4156200 см²

2. Second expression: 2563400 см² - 32 м² - 12 дм² Again, let's convert all units to square centimeters:

   • 32 m² = 32 * 10,000 cm²
   • 12 дм² = 12 * 100 cm²

   Now, we can calculate the second expression:

   2563400 см² - 32 * 10,000 cm² - 12 * 100 cm² = 2563400 см² - 320,000 cm² - 1,200 cm² = 2242200 см²

So, the simplified expressions are as follows:

First expression: 4156200 см² Second expression: 2242200 см²
