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?

Answer 1

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}.
