Beth needs 1 2/3 cups of sugar to make a cake and 2 1/4 cups to make a pie. how much sugar does she need to make both?

i believe it's a.

i'm not sure on this one, most likely correct.

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 : )
