The coordinate plane shows the floor plan for a swimming pool. What is the area of the pool’s border?

OpenStudy (anonymous):

Notice that all the triangles in this diagram are of the 3-4-5 proportions. You can, for example, find the length of the border by noticing that it hits at 9 and 12 so it must be 15 meters long. Use the same method to find the width. Use the same method to find the length and width of the pool. LW of border - lw of pool = answer.

OpenStudy (anonymous):

I figuared it out The area of the pool & border is A = Area L= Length = 15 W + widith = 10 A = 150 The pool area is L = 10 w= 5 A= 50 So the area of the perimeter = 100 square meters
