75 POINTS An empty lot with a width of 51.5 feet and a length of 30 feet has been approved for the development of a new playground. You are able to increase the length of playground by clearing some debris behind the lot. Write an expression to represent the total area of the playground. Be sure your expression accounts for the unknown amount of space you will gain by clearing debris.
Sketch a design for your playground. Split the lot into four sections using one vertical line and one horizontal line. Write an expression to represent the area of each section.
Make a model of your playground and the equipment that will be in each section. Use what you have learned about expressions to describe each section.
