This Instructional Activity is a part of the Lesson 15, Unit 4, Grade 7. Students solve area problems related to scale drawings and percent by using the fact that an area of a scale drawing is 𝑘^2 times the corresponding area in the original drawing, where 𝑘 is the scale factor. Students calculate the area in scale drawings and, through repeated calculations, generalize about the relationship between the area and the scale factor.
