Answer 1

This board of 24.5 inches long is not enough to be cut into the four walls of the bird house.

Explanation:

Hodi is building a birdhouse. Each of the four walls of the birdhouse needs to be 5.5 inches long.

So, to get four 5.5 inches long walls we need to have (5.5 × 4) = 22 inches ling board from which four equal 5.5 inches board can be made.

Now, Hodi has a piece of a board that is 24.5 inches long.

Therefore, this board is not enough to be cut into the four walls of the birdhouse. (Answer)
