A classroom board is 54 inches wide and 36 inches tall. Eva
is putting ribbon along the outside edge of the board. How
many inches of ribbon will she need?
36 inches
54 inches

Respuesta :

Answer:  180 inches

Work Shown:

L = 54 = length

W = 36 = width

P = 2(L+W) ... perimeter of the rectangle

P = 2(54+36)

P = 2(90)

P = 180

She needs 180 inches of ribbon.

To convert to feet, divide by 12. So 180 inches = 180/12 = 15 feet.
