Question

What is the perimeter of AWXY?

Answer 1

The Perimeter of WXY is 24 units .

To calculate the Perimeter, we find the length of all 3 sides of the triangle;

Using the distance formula :

• 
  `\sqrt{(x_(2) - x_(1))^(2) + (y_(2) - y_(1))^(2)}`

WX = (-10, 8) ; (-10, 0)

WX = √(-10 - (-10)) + (0 - 8)

WX = √0 + 64

WX = 8

XY = (-10, 8) ; (-4, 0)

XY = √(-4 - (-10)) + (0 -8)

XY = √36 + 64

XY = 10

WY = (-10, 0) ; (-4, 0)

WY = √(-4 - (-10)) + (0 - 0)

WY = √36 + 0

WY = 6

WX + XY + WY

= 8 + 10 + 6

= 24 units
