A classroom board is 36 inches tall and 54 inches wide. Cheryl is putting ribbon along the outside edge of the board, how many inches of ribbon will she need?
A. 180
B. 120
C. 90
D. 60
To find the amount of ribbon Cheryl will need, we need to find the perimeter of the board.
The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
Plugging in the values, we get P = 2(36) + 2(54) = 72 + 108 = 180 inches.
Therefore, Cheryl will need 180 inches of ribbon.
The answer is A. 180.
