Question

Find the area of shaded portion, where the length of it is $14$ units and radius of the upper semicircle is $7$ units.

• A. $196$
• B. $98$
• C. $200$
• D. None

Answer 1

The correct option is A $196$

Requried area of figure = Area of shaded portion
If we substract area of semi circle from area of rectangle & then add the area of upper semi circle, we get the net area or alternatively, if we calculate the area of rectangle, we get the net area = $l\times b$
$=14\times 14$
$=196$
