We continued our work with areas today by taking a look at how area and perimeter ratios can be determined between similar shapes. We reviewed how to find and work with the scale factor, and then showed some short cuts in doing these area ratio problems. We went over 4-5 examples together before getting started on the assignment.
Assignment: ratio of areas worksheet (#1-11) + section 11-7; page 458-459; WE #1-8, 10, 13, 23
