Use the quadrant system to find the area of the polygon

C. 18 square unit.

Step-by-step explanation:

Since, By the diagram we can say that,

The polygon is made by 4 rectangles in which,

Measurements of these rectangle are, 3 × 1, 4 × 1, 1 × 3, 4 × 2.

Thus, the total area of the given polygon = Total sum of the Area of these rectangles

A= 3 × 1 + 4 × 1 + 1 × 3 + 4 × 2= 3+4+3+8=18 square unit.

Thus, The area of given rectangle = 18 square unit.

Therefore Option C is correct.
