Bellringer • How could you solve this problem? • Denali and Mahala weed the borders on the north and south sides of their rectangular yard. Denali starts first and has weeded 1 m on the south side when Mahala says he should be weeding the north side. So, Denali moves to the north side. Mahala finishes weeding the south side. Then she moves to the north side where she weeds 2 m. Both students have then finished. Which student weeded more of the borders? How much more?
