Solution
The correct option is C 3
Number of full and more than half covered squares = 3
Ignore the squares that cover less than half area.
Area covered by full and more than half covered squares = 3 x 1 = 3 sq. cm
Area covered by less than half squares = 0
So, total area of the figure = 3 + 0 = 3 sq. cm
