Use the quadrant system to find the area of the polygon. a. 15 square units b. 16 square units c. 18 square units d. 17 square units

Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Dimensions of I st box as shown in the figure below:

Length = 5 units

Width = 2 units

So, Area of Ist box will be given as

Dimensions of II nd box as shown in the figure below:

Length = 2 units

Width = 1 unit

So, Area of II nd box will be given as

Similarly,

Dimensions of III rd box as shown in the figure below:

Length = 3 units

Width = 2 units

So, Area of III rd box will be given as

Total area of the polygon will be

Hence, Option 'C' is correct.
