7-125.

Ms. Jancsi bought a new package of border decoration to put around the bulletin board in her classroom. The package contains 300 inches of border. The dimensions of the rectangular bulletin board are 8 feet by 3 feet. If she puts the border around all four sides of the bulletin board, how much leftover bulletin material will she have? Include a labeled sketch in your answer. Homework Help ✎

Use the following sketch to help you find out how much leftover material Ms. Jancsi will have.

It may be useful to express all the lengths as inches.

8 feet is the same as 8 groups of 12 inches in each foot, or 8(12) = 96 inches.

Now, you can change the other side to inches and then find the perimeter of the bulletin board?
