After they share their answers, the following expressions are on the board:
Sam: 2(l+ w)
Joanna: l+w+l+w
Kiyo: 2l+ w
Erica: 2w + 2l

Which of the expressions are correct and how might the students have been thinking about finding the
perimeter of the rectangle?

Respuesta :

Sam and Erica are correct because if you multiply you l and w by two you would get the perimeter and also you can do the value of one w and multiply it by two and also the L hope it helps
