In this geometry warm-up session from April 18, 2011, we explore methods to find the area of various shapes, including regular polygons and circles. We will solve problems such as determining the area of a lawn surrounding a rose garden and calculating the area of a regular pentagon with a perimeter of 90 meters. Additionally, we will address the area of shaded regions in circles, reinforcing our understanding of geometric area concepts. Join us as we enhance our skills in finding areas in different geometrical contexts.
