Open Up Resources 40 min(s)

Calculate areas of polygons. Let's estimate the areas of weird shapes. The purpose of this lesson is for students to practice composing and decomposing irregular regions to calculate their area, in preparation for estimating the area of circles in the next lesson. In the first activity, the region is polygonal and students can calculate an exact answer for the area of the floorplan.
