+2 area of square   =   ( side length )2

And the side length is the length of the line segment between  (-7, 2)  and  (0, 8)

By the Pythagorean Theorem,

( side length )2   =   ( 0 - -7)2  +  (8 - 2)2

( side length )2   =   72  +  62

( side length )2   =   49 + 36

( side length )2   =   85

And again       area of square   =   ( side length )2

We just found that     ( side length )2  =  85     So...

area of square   =   85
