Solution
The correct option is D (a) and (c) above. To find out the area of the crazy shapes, we have to count the number of squares occupying the space inside the shapes.
For a:
Since 31 small squares of unit area each entirely occupy the space inside the shape, the area of the shape is 31 square units.
For b:
This shape is made up of 32 small squares, so its area is 32 square units.
For c:
Similary for this shape, we can see 31 small squares of unit area covers the area thus its area is also 31 square units.
