Solution Steps

Step 1: Analyze the given land area

The land area of Montana is given as \( 145,546 \) square miles.

Step 2: Check option A (nearest ten)

To round \( 145,546 \) to the nearest ten:

  • Look at the ones digit, which is \( 6 \).
  • Since \( 6 \geq 5 \), round up the tens digit by \( 1 \).
  • The rounded value is \( 145,550 \).
  • Option A is true.
Step 3: Check option B (nearest hundred)

To round \( 145,546 \) to the nearest hundred:

  • Look at the tens digit, which is \( 4 \).
  • Since \( 4 < 5 \), keep the hundreds digit the same.
  • The rounded value is \( 145,500 \).
  • Option B is false.
Step 4: Check option C (nearest thousand)

To round \( 145,546 \) to the nearest thousand:

  • Look at the hundreds digit, which is \( 5 \).
  • Since \( 5 \geq 5 \), round up the thousands digit by \( 1 \).
  • The rounded value is \( 146,000 \).
  • Option C is false.

Final Answer
