Question

Each small square on the grid is 1 cm².

Answer 1

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

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.

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

The area of a parallelogram is 12 cm square.

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

$\text{Area of a triangle}=\frac{1}{2}\times 2\times 0.25=0.25$

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.

Answer 2

Answer:

25 units²

Step-by-step explanation:

Count each whole box as one cm and count the ones that aren't whole as half a cm and you get 25 units²
