To find the area of the rectangular section of wilderness, we can use the formula for the area of a rectangle:

\[ \text{Area} = \text{length} \times \text{width} \]

Given the dimensions in scientific notation:

  • Length: \( 6 \times 10^3 \) meters
  • Width: \( 3 \times 10^4 \) meters

Now, we can calculate the area:

\[ \text{Area} = (6 \times 10^3) \times (3 \times 10^4) \]

Using the associative property of multiplication, we can rearrange the multiplication:

\[ \text{Area} = (6 \times 3) \times (10^3 \times 10^4) \]

Calculating the numerical part:

\[ 6 \times 3 = 18 \]

For the powers of 10:

\[ 10^3 \times 10^4 = 10^{3+4} = 10^7 \]

Now, combining both parts, we get:

\[ \text{Area} = 18 \times 10^7 \]

Now, we can convert \( 18 \) into scientific notation:

\[ 18 = 1.8 \times 10^1 \]

Substituting this back into the area calculation gives us:

\[ \text{Area} = (1.8 \times 10^1) \times 10^7 \]

Using the property of exponents:

\[ \text{Area} = 1.8 \times 10^{1+7} = 1.8 \times 10^8 \]

Thus, the area of the land in square meters, in scientific notation, is:

\[ \boxed{1.8 \times 10^8} \]

\[ \text{Area} = (6 \times 10^3) \times (3 \times 10^4) = 18 \times 10^7 = 1.8 \times 10^8 , \text{m}^2 \]

\[ \text{Answer: } \boxed{1.8 \times 10^8} \]
