5 * 4 = ?
Let's assume the length of the original piece of fabric is 'x' feet. After Bernadette cuts off 3 feet from one of the pieces, she is left with a piece that is 2 feet long. Therefore, the length of this piece before the cut was 2 feet + 3 feet = 5 feet.
Since she divided the piece of fabric into four equal pieces, each of the four pieces would have been 5 feet in length before the cut.
Therefore, the length of the original piece of fabric is 4 times 5 feet = 20 feet.
So, Bernadette started with a piece of fabric that was 20 feet long.
