The students in Mr. Nolan's class are writing expressions for the perimeter of a rectangle of side length & and width w.
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?
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
