Find the total shaded area of the figure made up of identical squares.

• A. $38c{m}^2$
• B. $243c{m}^2$
• C. $171c{m}^2$
• D. $196c{m}^2$

Answer 1

The correct option is C $171c{m}^2$

Area of $1$ small square$=(3\times 3)c{m}^2$
$=9c{m}^2$
Number of shaded squares$=19$
$\therefore$ Shaded area$=19\times 9=171c{m}^2$.
