Derek is building a bird feeder to sell at a crafts fair. He is using a board that is 4 feet long. He will cut one piece that is 2 feet long for the base. Then he will use the rest of the board and cut it into two pieces of equal length for the sides. If he puts the and one of the sides together first, what fraction of the total board will he have used?

This doesn't make much sense. Please correct this sentence and repost.

Ms. Sue,
Sorry. The question is If he puts the base and one of the sides together first, what fraction of the total board will he have used? 
3/4

Can you please show me how to work out the problem so that I can understand it?

He started with a 4foot piece. He then cut off 2 feet, leaving a 2foot piece. 2/4 = 1/2 remains.
He used 1/2 of what was left.
1/2 * 1/2 = 1/4
4/4  1/4 = 3/4 
Thanks Ms. Sue!
