Camping Choices

Cori and three friends are going camping. 

  • They will share one tent, and they want a large enough tent to fit just their sleeping bags. 
  • Their sleeping bags are rectangular and all the same size.
  • When purchasing a tent, the package is labeled with the dimensions of the rectangular base. 

What size of tent should they buy? What could the dimensions of the rectangular base be? What could the area of the base be?
