The residents of Watson Avenue are decorating their houses for the upcoming holidays. They have decided to all string lights around the roofs of their houses. How many feet of lighting
does Sarina need if she wants to string lights along roof?
4 feet
- 10 feet -
6 feet
6 feet
6 feet
6 feet

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
