Xiaohong's art club wants to publish a calligraphy work. The work itself is 5 feet long and 3 feet wide, and the edges of the framed lace are the same width, so that the whole after mounting is completed.
If the width of lace is x feet, the length of framed lace is (5+2x) feet, the width is (3+2x) feet, and the area is 24 square feet.
According to the topic, (5+2x)(3+2x)=24, the solution is x=0.5, and the other solution is -4.5, which is discarded.
Therefore, the surrounding lace is 0.5 feet wide.
