  1. Draw a picture. Make a big rectangle that has dimensions 60x100. Inside that rectangle, make a smaller rectangle with dimensions 30x50. Based on the picture, what do you think you should do to solve for the lawn?

  2. oh ok :) So then, would I multiply 60x100=6000
    and 30x50=1500
    then subtract 6000-1500?
