A classroom board is 48 inches wide and 32 inches tall. Aba is putting ribbon along the outside edge of the board. How many inches of ribbon will she need?

1 answer

To find the total length of the ribbon needed, we need to add up the lengths of all four sides of the board.

The top and bottom sides both have a length of 48 inches.
So, the total length of the top and bottom sides is 48 + 48 = <<48+48=96>>96 inches.

The left and right sides both have a length of 32 inches.
So, the total length of the left and right sides is 32 + 32 = <<32+32=64>>64 inches.

Therefore, Aba needs a total of 96 + 64 = <<96+64=160>>160 inches of ribbon. Answer: \boxed{160}.
