I need help with a math problem
This week, I'm studying the axis of symmetry and vertexes in my math class. I'm having trouble with the word problems. Here's one of them: A gardener has enough money to build 260 feet of garden wall. He plans to use an existing wall for one side of the enclosure. What is the largest rectangular area he can enclose?
If someone could explain how to work this problem, or give me a website or video link that shows how to work these types of problems, that would be great. Thanks in advance!
