Natalie used 112 inches of blue yarn as a border her rectangular bulletin board. If the bulletin board is 36 inches wide, how lo ng is it?
2 answers:
The answer is 20 inches long
36x2(for the total amount of yarn for the width) would be 72. 112-72=40. Since it is a rectangle and the width should both be the same size, the length should be 20 inches. (20+20+36+36=112, so 20 inches is the correct answer.
