a^2 =121
a=11
length of wire =4a =44
2pi r =44
r=7
area = pi r^2
A = 22/7 x(7×7) =154 sqm

Rudra18328: Can explain it how r=7
Rudra18328: Please
dineshmehta1991: 2 x( 22/7) x r =44
dineshmehta1991: hence (44/7)xr = 44
dineshmehta1991: r =7
Rudra18328: O thanks bro
dineshmehta1991: because length of the wire will act as circumference of circle
Rudra18328: Ok
dineshmehta1991: welcome
