Question

the area of square is 101+1÷400.find the length of one side of the field

Answer 1

101+1/400
101+0.0025
101.0025

area=s^2
101.0025=s^2
root 101.0025=s
10.05=s

the side is 10.05 units

Answer 2

$area = \frac{101 + 1}{400}$

$area = \frac{102}{400} = {a}^{2}$

${a }^{2} = \frac{51}{200}$
$a = \sqrt{ \frac{51}{200} }$
