Answer:
168 kilometers²
Step-by-step explanation:
Area of a rectangle =l×b/w
13×7=91
Area of a triangle =½(b×h)
½(14×11)
½×154=77
Sum of area of both shapes=area of the figure
91+77=168
well, let's simply get the area of each figure, sum them up and that's the area of the composite shape with the triangle and rectangle.
[tex]\stackrel{\textit{\large Areas}}{\stackrel{rectangle}{(13\cdot 7)}~~ + ~~\stackrel{triangle}{\left[\cfrac{1}{2}(\stackrel{b}{14})(\stackrel{h}{11}) \right]}}\implies 91~~ + ~~77\implies 168[/tex]
