Question

Answer 1

[ 1 Mark ]
Number of full and more than half covered squares = 10
Ignore the squares that cover less than half area.
Area covered by full and more than half covered squares = 10 x 1 = 10 sq. cm [ 1 Mark ]
Area covered by less than half squares = 0
So, total area of the figure = 10 + 0 = 10 sq. cm [ 1 Mark ]
