Answer: The correct option is option third, i.e.,25 cm square.

Step-by-step explanation:

From the given figure it is easily noticed that the shaded region contains two congruent parallelograms and 4 congruent triangles.

Area of a parallelogram is the product of base and height.


\text{Area of a parallelogram}=4* 3=12

The area of a parallelogram is 12 cm square.

Area of a triangle is half of the product of base and height.


\text{Area of a triangle}=(1)/(2)* 2* 0.25=0.25

The area of a triangle is 0.25 cm square.

Since there are 2 parallelograms and 4 triangles in the figure, therefore the total area is,


A=2(12)+4(0.25)


A=24+1=25

Therefore, the area of figure is 25 cm square and the third option is correct.
