A classroom board is 30 inch wide and 18 inch tall Gil is putting ribbon along the outside edge of the board how many inches of ribbon will he need

1 answer

To calculate the amount of ribbon needed, we need to find the perimeter of the board.

Perimeter = 2(width) + 2(height)
Perimeter = 2(30 inches) + 2(18 inches)
Perimeter = 60 inches + 36 inches
Perimeter = 96 inches

Therefore, Gil will need 96 inches of ribbon to go along the outside edge of the board.
