Answer:


Perimeter = 11 + √(13)

Explanation:

To find the perimeter of WXYZ we need to find the length of all four sides: WX, XY, YZ and WZ.

To find the length of each side, we can use the formula for the distance of two points:


distance = √((x_1 - x_2)^2 + (y_1 - y_2)^2)

So we have that:


WX = √((2 - 4)^2 + (3 - 6)^2) = √(13)


XY = √((4 - 7)^2 + (6 - 6)^2) = 3


YZ = √((7 - 7)^2 + (6 - 3)^2) = 3


WZ = √((2 - 7)^2 + (3 - 3)^2) = 5

The perimeter is:


Perimeter = WX + XY + YZ + WZ


Perimeter = √(13) + 3 + 3 + 5 =11 + √(13)
