To find the missing length \( w \) using the given area and one of the lengths, we can use the formula for the area of a rectangle:
\[
\text{Area} = \text{Length} \times \text{Width}
\]
In this case, the length is given as \( 7 \, \text{km} \) and the area is given as \( 28 \, \text{km}^2 \). We need to find \( w \):
\[
28 \, \text{km}^2 = 7 \, \text{km} \times w
\]
To isolate \( w \), divide both sides of the equation by \( 7 \, \text{km} \):
\[
w = \frac{28 \, \text{km}^2}{7 \, \text{km}} = 4 \, \text{km}
\]
So, the missing length \( w \) is \( 4 \, \text{km} \).
\[
\text{Area} = \text{Length} \times \text{Width}
\]
In this case, the length is given as \( 7 \, \text{km} \) and the area is given as \( 28 \, \text{km}^2 \). We need to find \( w \):

28 \, \text{km}^2 = 7 \, \text{km} \times w

w = \frac{28 \, \text{km}^2}{7 \, \text{km}} = 4 \, \text{km}
\]
So, the missing length \( w \) is \( 4 \, \text{km} \).
