Answer 2

Option C is the correct answer.

Explanation:

If we examine the given figure we can see 27 square boxes and 4 triangles inside the blue line.

Area of 1 square box = 1 inch²

Area of 1 triangle portion = 0.5 inch²

Total area = 27 x 1 + 4 x 0.5 = 27 + 2 = 29 inch²

Area of the figure = 29 inch²

Option C is the correct answer.
