Question

.Find the area of the polygon with the given vertices.

E(3,\ 1),\ F(3,-2),\ G(-2,-2)$

The area is
square units.

Answer 1

To solve this problem you must apply the proccedure shown below:

1. Plot the points, as you can see in the graph attached.
2. Now, by using the dimensions observed in the graph, you need to apply the formula for calculate the area of a triangle, where $b$ is the base and $h$ is the height.
3. Now, substitute values and then, you obtain:

$A=\frac{(b)(h)}{2} \\ A=\frac{(5units)(3units)}{2}\\ A=7.5units^{2}$

Therefore, the answer is: $7.5units^{2}$
