Symmetric L-Shape
Symmetric L-Shape: a composite plane figure made of a square with side 6.6 cm, minus a square with side 8.4 cm. It is a classic primary school geometry problem (“Orthogonal Profiles”). The net area is 25.92 cm² and the total perimeter is 26.4 cm.

Area of each basic shape before the Boolean composition.
How to find the area
Area formula: A = L² − l²
The parts overlap or intersect, so the net area (25.92 cm²) comes from the exact Boolean operation rather than from a plain sum of the part areas.
