Sydney is saving money and plans on making annual contributions into an account earning an annual interest rate of 7% compounded annually. If Sydney would like to end up with $9,000 after 12 years, how much does she need to contribute to the account every year, to the nearest dollar? Use the following formula to determine your answer. (Annuities - Find Payment Amount)

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 : )
