This math topic focuses on calculating the total area of rectangles given the area of a fractionally filled part. Each question provides the area of a rectangle section that represents a fraction (e.g., 1/4, 1/2, 2/4, 3/4) of the entire shape and requires calculating the area of the full rectangle based on this information. This challenges learners to apply concepts of area, decimal and fractional multiplication, and proportionality within a real-life context, and is part of an introductory unit on area and perimeter logic.
