The length of a rectangle is two - fifths of the radius of a circle. The radius of the circle is equal to the side of the square, whose area is 100 sq.units. What is the area (in sq.units) of the rectangle if the rectangle if the breadth is 2 units?  Options
A) 140 sq.units
B) 158 sq.units
C) 8 sq.units
D) 607 sq.units
E) 815 sq.units
Given that the area of the square = 100 sq.units   =&gt; Side of square = √100= 10 units   The radius of the circle = side of the square = 10 units   Length of the rectangle = 2/5 * 10=
