Question

how can you find the area of the shaded polygon? i can add the area of the two triangles. what is the area of the top triangle? area of the top triangle = 9 square units. what is the area of the bottom triangle? area of the bottom triangle = square units

Explanation:

Step1: Recall triangle - area formula

The formula for the area of a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height.

Step2: Determine base and height of bottom - triangle

Assume from the grid that the base $b$ of the bottom - triangle is 6 units and the height $h$ is 3 units.

Step3: Calculate area of bottom - triangle

$A=\frac{1}{2}\times6\times3 = 9$ square units.
