Question

In the given figure, a semi circle is cut out of rectangle.Find the area of shaded portion, where the length of rectangle is $14\text{units}$ and radius of the upper semicircle is $7\text{units}$.

• A. $196$
• B. $219$
• C. $124$
• D. $358$

Answer 1

The correct option is A $196$

Required area of figure $=$ Area of shaded portion
If we subtract area of semi-circle from area of rectangle and then add the area of upper Semi-circle, we get the net area of alternatively, if we calculate the area of rectangle,
we get the net area $=l\times b$
$=14\times 14$
$=196$
