Question

9смкв×440м кв/5500см кв－235см кв

Answer 1

9 см2 × 4 = 36 см2
40 м2 ÷ 5 = 8 м2
500 см2 - 235 см2 = 265 см2

Answer 2

To solve the expression, let's break it down step by step:

1. 9 cm^2 × 440 m^2: Since the units are different (cm^2 and m^2), we need to convert one of them to match the other. We can convert cm^2 to m^2 by dividing by 10,000 (since 1 m^2 = 10,000 cm^2).

9 cm^2 = 9 / 10,000 m^2 = 0.0009 m^2

Now, the expression becomes: 0.0009 m^2 × 440 m^2

2. Now, we can multiply the two areas:

0.0009 m^2 × 440 m^2 = 0.396 m^4 (square meters squared)

3. Next, we have: 5500 cm^2 - 235 cm^2

Since the units are the same (cm^2), we can directly subtract:

5500 cm^2 - 235 cm^2 = 5265 cm^2

4. Finally, we need to convert cm^2 to m^2 by dividing by 10,000:

5265 cm^2 = 5265 / 10,000 m^2 = 0.5265 m^2

Now, the final result is the difference between the two areas:

0.396 m^4 - 0.5265 m^2

And this cannot be simplified further as the units are different. So the final result is:

0.396 m^4 - 0.5265 m^2
