Hello Cassandra, I hope you are well. I really enjoyed reading through your response. This is an excellent response! You used real world applications and even gave the equation that you would use. This is something that I personally struggle with. Yes, I know what to measure, but putting it together I get confused. It's been many, many moons since I have done math like this and anytime I have needed things done to my house, I have had professionals do it. This really gave me a better understanding and I am very grateful!
