Choose the correct choice from the following choices.
A) 3284.28678	B) 3184.28678	C) 3084.28678	D) 4184.28678	E) 2184.28678
Let Diagonals of Rhombus are p,q and side is a .   Let Longest side is one of the p and q, let its p=80;   Area of a Rhombus is A =p*q/2   A=2400   2400=80 *q /2   4800=80q=&gt; q=60   4a^2 =60^2 + 80^2   4a^2=10,000=&gt; a=&gt;50   Given: Perimeter of R = Perimeter of Circle   4a = 2*3.14* r=&gt; r=31.84   Area of circle = 3.14* r^2 = 3184.28678   ANSWER:3184.28678
