This math topic focuses on calculating the area of an obtuse triangle within a complex shape, specifically using given dimensions. It is aimed at enhancing understanding of area and perimeter within more intricate geometric configurations. Each question presents a diagram with a shaded obtuse triangle section, and the task is to determine its area. Additionally, the topic integrates these practical skills into the broader context of dealing with complex shapes, aligning with mathematical concepts relevant to geometry.
