Can someone please help me with this Geometry problem?

Question

What is the perimeter of rectangle WXYZ with coordinates W (3, -4), X(3, -6), Y(-1, -6), and Z (-1, -4)?

I got 11, is this correct?

Answer 1

Find the Sides

WX= 2

XY =4

YZ =2

ZW = 4

For finding sides Use

WX = Sqrt ⌈( y2 - Y1 )² +( X2 - X1 )² ⌉ = sqrt 4 = 2
