Hope it will help u

Answer 2

HELLO DEAR,



let the radius be R

circumference of a circular field =2πR=220m


$2\pi \: R = 220 \\ = > 2 \times \frac{22}{7} \times R = 220 \\ = > R = \frac{220 \times 7}{22 \times 2} \\ = > R = \frac{10 \times 7}{2} \\ = > R = 5 \times 7 \\ = > R = 35m$
now the area of the field=πR²
where radius =(R=35)

$\pi {R}^{2} = \frac{22}{7} \times {35}^{2} \\ = > \frac{22}{7} \times 1225 = 22 \times 175 \\ = > 3850 {m}^{2}$

I HOPE ITS HELP YOU DEAR,
THANKS
