The fourth graders of Guangming Primary School planned to line up in a square queue to participate in the broadcasting exercise performance. Due to insufficient costumes, we had to reduce the horizontal and vertical rows by one row, so that a total of 27 people need to be removed. Ask: How many people were originally prepared to participate in the performance in the fourth grade?
光明小学四年级原准备排成一个正方形队列参加广播操表演．由于服装不够，只好横竖排各减少一排，这样共需去掉27人，问：四年级原来准备多少人参加表演？
