Question

A polygon has vertices A(3,3), B(3,6), and C(8,3). find the area of the polygon.

Answer 1

The polygon with three vertices is,

The polygon is triangle with base b = 5 units and height h = 3 units.

Determine the area of polygon.

`\begin{gathered} A=(1)/(2)\cdot b\cdot h \\ =(1)/(2)\cdot5\cdot3 \\ =(15)/(2) \\ =7.5 \end{gathered}`

So area of figure is 7.5 square unit.
