Area of an Obtuse Triangle - Center of Square (from Perimeter) (Level 1)

This math topic focuses on calculating the area of shaded regions within a square, where the shaded region is an obtuse triangle. Each question presents a diagram with a square and an obtuse triangle inside it, and the task is to determine the area of the triangle. The skills practiced include understanding geometric shapes, specifically squares and obtuse triangles, and applying area calculations in a complex shape context. This forms part of a broader theme on area and perimeter of complex shapes, enhancing spatial reasoning and application of geometric formulas.
