What is the area (in square units)?

 

What is the length of one of its diagonals (in units)?

Use distance formula twice to find side lengths

WX = sqrt (6^2 +2^2 ) = sqrt 40

WZ = sqrt ( 9^2 +3^2) = sqrt 90

 

Area = sqrt(40*90) = 60 units2

 

To find the diagonal use distance formula from W to Y

 

or    sqrt (   sqrt(40)^2 + (sqrt(90)^2 ) =sqrt 130
