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 8100 sq.units. What is the area (in sq.units) of the rectangle if the rectangle if the breadth is 10 units? Choose the correct choice from the following options.
A) 140 sq.units
B) 360 sq.units
C) 367sq.units
D) 178sq.units
E) 176sq.units
Given that the area of the square = 8100 sq.units   =&gt; Side of square = √8100 = 90 units   The radius of the circle = side of the square = 90 units Length of the rectangle = 2/5 * 90=
