Arsema, Balqiisa and Chamoya won a team art competition at their local park. As part of their prize, they could paint the 1 km (1000 m) perimeter fencing around their local park any way they like. They decided Arsema will paint the first 11 m, then Balqiisa will paint the next 12 m, then Chamoya will paint the next 15 m. They will keep repeating this pattern until they reach the end of the 1 km perimeter.
