3. A farmer in St. Mary’s rural parish broke his leg, just at harvest time. Two neighbouring farmers, also members of the parish, heard of his plight, and offered to help by cutting and baling the hay in his far field. The field is 40 m by 25 m. The two helpers agreed that one would start at one corner, and mow around the edge, spiraling inward until he had cut half of the field. Then the second farmer would finish mowing the rest of the field. What width of a section would the first farmer cut, before handing the job over to his friend? See the diagram below to illustrate the plan:
