Because sun spots appear to move across the surface due to the sun's rotation. Observe the sun by projecting its image onto a piece of paper through binoculars or a small telescope. (Never look directly at the sun of course with or without binoculars or telescope unless you want to immediately go permanently blind!) Observe over a few weeks day by day and note the time when a sun spot just appears at the edge of the sun. Track this spot day by day and note the day when it reaches the other side and disappears. It will therefore have appeared to travel over half the sun's surface (the half we can see) because of the sun's rotation. If you double this figure (to take into account the apparent journey across the surface of the sun that we cannot see) then this figure will be the time for the sun's rotation.
