Answer:
6,4
Step-by-step explanation:
One way is to calculate the distance between W and X, and X and Y to find the length and width.
The distance formula: [tex]d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
plug W(1,-2) and X(7,-2) in to get the length
[tex]\sqrt{(1-7)^2+(-2-(-2))^2}=\sqrt{(-6)^2 +0^2}=\sqrt{36} =6[/tex]
plug X(7,-2) and Y(7,-6) to get the width
[tex]\sqrt{(7-7)^2+(-2-(-6))^2}=\sqrt{0^2 +4^2}=\sqrt{16} =4[/tex]
