Question

please find the ans this is very important

Answer 1

Let the length and breadth be 2x, x respectively.
Area of the rectangle = l*b
$= {2x}^{2}$
Perimeter of the rectangle = 2(l+b)= 2(2x+ x) = 6x
P of rectangle = C of circle
6x= 2pi*r
6x = 2*22/7r
r = 6x*7/2*22
r = 21x/22
A of circle = 22/7*21x/22*21x/22
$= 42 {x}^{2} \div 22$
A of circle = A of rectangle +104.5
$42 {x}^{2} \div 22 = 2 {x}^{2} + 104.5$
42x2-2299/22=2x2
42x2-2299=44x2
2299= (44-42)x2
2299= 2x2
2299/2=x2
$\sqrt{1149.5} = x$
x = 33.9
2x = 2*33.9 = 67.8cm
