Add up all the sides to get the perimeter:

Answer:
Step-by-step explanation:
Let Kaylee used the amount of green paint in the mixture = x ounces
and the amount of white paint = y ounces
Total amount of mixture = 50 ounces
Equation will be x + y = 50 ------(1)
Ratio of green paint to the white paint in the mixture = 5 : 3
⇒ x : y = 5 : 3
⇒ 
⇒ x =
---------(2)
Therefore, By solving these two equations by substitution method we can get the amount of green and white paint used in the mixture.
