Area of an Obtuse Triangle - Center of Square (from Perimeter) (Level 3)

This math topic focuses on calculating the area of shaded obtuse triangles within squares, based on their perimeters. It is aimed at enhancing proficiency in understanding spatial relationships in geometry, specifically in contexts where triangles are positioned within other shapes. The questions involve various configurations of triangles and squares, requiring learners to apply area formulas and possibly other geometric principles to determine the correct shaded area. Each problem presents a diagram and multiple choice answers, pushing learners to visually interpret and solve the problems accurately.
