Given:

The figure is given.

To find:

The Area of the figure.

Step-by-step explanation:

Let us find the area of the triangle.

The base of the triangle is 7km.

The height of the triangle is 10km.

Using the area of the triangle formula,


\begin{gathered} A=(1)/(2)bh \\ =(1)/(2)*7*10 \\ A=35km^2 \end{gathered}

Let us find the area of the bottom rectangle.

The length of the rectangle is 7km.

The breadth of the rectangle is 8km.

Using the area of the rectangle,


\begin{gathered} A=lb \\ =7*8 \\ A=56km^2 \end{gathered}

Let us find the area of the right side rectangle.

The length of the rectangle is 9km.

The breadth of the rectangle is 6km.

Using the area of the rectangle,


\begin{gathered} A=lb \\ =9*6 \\ A=54km^2 \end{gathered}

Summing up the areas we get,


\begin{gathered} A=35+56+54 \\ A=145km^2 \end{gathered}

Therefore, the area of the figure is 145 square km.

Final answer:

The area of the figure is 145 square km.
