And Answers With Compete Solutions
A rectangular message board in Aleyah's dormitory room has a length of 30
inches and a perimeter of 108 inches. A rectangular bulletin board in the hallway
outside Aleyah's room is twice as long and twice as wide as the message board.
Which of the following statements about the bulletin board is true?
The bulletin board has a width of 48 inches.
The bulletin board has a length of 96 inches.
The area of the bulletin board is twice the area of the message board.
The perimeter of the bulletin board is four times the perimeter of the message
board.
Option (A) is correct. Since the message board has a length of 30 inches and a
perimeter of 108 inches, the width of the message board can be found by solving the
equation 2(30)+2w=108 for w. To solve the equation for w, subtract 60 from both sides
of the equation and then divide both sides of the equation by 2 to find that w=24. This
means that the length and width of the bulletin board are 60 inches and 48 inches,
respectively, and it can be concluded that the area of the message board is 720 square
inches, the perimeter of the bulletin board is 216 inches, and the area of the bulletin
board is 2,880 square inches. Thus, the only true statement is that the bulletin board
has a width of 48 inches.
