Lines k and n are perpendicular. if the slope of line k is -6, what is the slope of line n?

a. 6
b. 1/6
c. -6
d. -1/6

For perpendicular lines:
"Their slopes' product is -1"

According to this rule:
the slope of line n is the negative of the reciprocal of the line k's slope

 

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
