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
