Question

WILL AWARD BRAINIEST: Find the area of the shaded polygons below:

Answer 1

Answer:

9 square units

Step-by-step explanation:

You can use the Pick's formula:

$A=i+\dfrac{b}{2}-1$

Where

$i$ - the number of lattice points inside the polygon

$b$ - number of lattice points on the border located on the perimeter of the polygon

From the picture we have:

$i=5\\\\b=10$

Substitute:

$A=5+\dfrac{1}{2}\cdot10-1=5+5-1=10-1=9$
