To find the total area covered by the national park and the national forest combined, we simply add their areas together:
- National park: \( 1.42 \times 10^6 \) acres
- National forest: \( 1.2 \times 10^6 \) acres
Now add them:
\[ 1.42 \times 10^6 + 1.2 \times 10^6 = (1.42 + 1.2) \times 10^6 = 2.62 \times 10^6 \]
So, the total area in acres is \( 2.62 \times 10^6 \) acres.
The correct response is:
2.62×10^6
