Paula completely covered a square wall using 87.5 ft2 of wallpaper without any overlap. which measurement is closest to the side length of this wall in feet? a) 22ft b) 44ft c) 9ft d) 7ft

The answer is B) 44ft

1. find the coordinates of b, c, e and f
b(-2,4)
c(1,1)
e(4,4)
f(6,2)

2. use the formula:
m=y2-y1/x2-x1

3. slope of bc
m=1-4/)
m=-3/3
m=-1

4. slope of ef
m=2-4/6-4
m=-2/2
m=-1

5. so both of the line segments have the slope of -1, have a nice day : d
