Tom and Jerry decide to find the perimeter of their garden. Tom measures the length as 5.2 metres while Jerry measures the width as 370 cm. What is the perimeter?
i did 3.7 + 5.2 = 8.9 m is that correct?

I'm afraid not. The perimeter of a rectangle is twice the length plus twice the width. (P = 2L + 2W.) Care to try again? (BTW, good job converting from cm to m.)
would it be 3.7m + 3.7m + 5.2m + 5.2m = 17.8m
