Part a
Find out the area of the given rectangle
The area of the rectangle is given by the formula
[tex]A=L*W[/tex]
where
L=13 km
W=5 km
Substitute
[tex]\begin{gathered} A=13*5 \\ A=65\text{ km}^2 \end{gathered}[/tex]
The area is 65 square kilometers
Part b
Find out the perimeter
The perimeter is given by the formula
[tex]\begin{gathered} P=2L+2W \\ substitute\text{ values} \\ P=2(13)+2(5) \\ P=26+10 \\ P=36\text{ km} \end{gathered}[/tex]
The perimeter is 36 km
