Point (2,3) is the vertex of a square, and point (−2,7) is the opposite vertex of the same square means (2,3) and (-2,7) are vertices of diagonal

Distance between (2,3) and (-2,7) =$$\sqrt{(2+2)^2+(3-7)^2}$$=$$\sqrt{2*16}$$

Area of square in terms of diagonal =$$\frac{1}{2}d^2$$

=(1/2)2*16

=16

Hence C

use distance formula
we get diagonal of square = 4 sqrt 2
so side = s sqrt2 = 4 sqrt2
s= 4
area = 16
