Answer» Given,Side of Square S = (x + 1)/2 Diagonal of square = (3-x)/root(2) We know,Diagonal of square = sideroot(2) Therefore,(3-x)/root(2) = [(x + 1)/2]root(2)(3-x) = (x + 1)2x = 2x = 1 (C) is correct option

Answer»

Given,Side of Square S = (x + 1)/2

Diagonal of square = (3-x)/root(2)

We know,Diagonal of square = side*root(2)

Therefore,(3-x)/root(2) = [(x + 1)/2]*root(2)(3-x) = (x + 1)2x = 2x = 1
