Area, x = a*b; x = 1
Therefore 1 = a*b_________________ Eq .1
Ratio of sides a and b, a/b, is √2,
Therefore a/b = √2
Hence a = (√2)*b__________________Eq. 2
Eq.2 in Eq.1:
1 = [(√2)*b]*b
1 = (√2)*bsqared
bsquared = 1/√2
b = √(1/√2)
Replace value of b into Eq. 2
Therefore a = (√2)* √(1/√2)
Hence value a = (√2)* √(1/√2) and b = √(1/√2). (Surd format )
