Answer:
(a) Number of filled square = 9
\therefore∴ Area covered by squares = 9 x 1 = 9 sq. units
(b) Number of filled squares = 5
\therefore∴ Area covered by filled squares = 5 x 1 = 5 sq. units
(c) Number of full filled squares = 2
Number of half filled squares = 4
\therefore∴ Area covered by full filled squares = 2 x 1 = 2 sq. units
And Area covered by half filled squares = x = 2 sq. units
\therefore∴ Total area = 2 + 2 = 4 sq. units
(d) Number of filled squares = 8
\therefore∴ Area covered by filled squares = 8 x 1 = 8 sq. units
