Understand relationship scale factor: Understand the relationship between the scale factor and the area of similar polygons.When a polygon is scaled by a factor of k, the area of the polygon is scaled by a factor of k2. This is because area is a two-dimensional measurement, and scaling affects both dimensions (length and width).
Calculate scale factor squared: Calculate the scale factor squared. Since the scale factor is 21, we square it to find the factor by which the area will be scaled. (21)2=41
Apply scale factor to area: Apply the scale factor squared to the area of Polygon C to find the area of Polygon D.The area of Polygon C is 40 square units. We multiply this by the scale factor squared to find the area of Polygon D.Area of Polygon D = Area of Polygon C × (Scale factor squared)Area of Polygon D = 40×(41)
Perform multiplication for area: Perform the multiplication to find the area of Polygon D.Area of Polygon D = 40×41Area of Polygon D = 440Area of Polygon D = 10
