Question

The area of the shaded region is

• A. $150c{m}^2$
• B. $140c{m}^2$
• C. $205c{m}^2$
• D. $120c{m}^2$

Answer 1

The correct option is C $205c{m}^2$

Draw three straight lined and cut the shaded portion into three rectangles of $(15\times 3),(10\times 4)$ and $(15\times 8)$
$\therefore$ total area $=(15\times 3)+(10\times 4)+(15\times 8)$
$=45+40+120$
$=205c{m}^2$
