Math Problem Statement
An art classroom has both rectangular and circular tables. The teacher plans to cover each table with a sheet of paper for students to work on. What area of paper should the teacher cut for each rectangular and circular table? There are 12 identical rectangular tables and 6 identical circular tables. What is the total area of paper needed for all the tables?
Solution
Let's work through this problem together:
Part a:
You are asked to find the area of paper that should be cut for each rectangular table.
- The dimensions of the rectangular table are given as 6 ft (length) by 2 ft (width).
- The area of a rectangle is calculated using the formula: Substituting the values: So, the area of paper for each rectangular table is 12 square feet.
For the circular table, the diameter is given as 2.6 ft.
- The area of a circle is calculated using the formula: where is the radius. Since the diameter is 2.6 ft, the radius is: Substituting the values into the area formula: So, the area of paper needed for each circular table is approximately 5.3 square feet (rounded to the nearest tenth).
Part b:
Now, there are 12 identical rectangular tables and 6 identical circular tables. You need to find the total area of paper needed for all the tables.
- Total area for rectangular tables:
- Total area for circular tables:
- Total area for all the tables: Rounded to the nearest tenth, the total area of paper needed is 175.9 square feet.

Tip:
When calculating the area of circular shapes, always use the radius, which is half of the diameter, and ensure to round only at the final step for better accuracy.
