Classic T-Shape
Classic T-Shape: a composite plane figure made of a rectangle 2.4 × 5.2 cm, joined with a rectangle 6.8 × 2.2 cm. It is a classic primary school geometry problem (“Orthogonal Profiles”). The net area is 27.44 cm² and the total perimeter is 28.4 cm.

Area of each basic shape before the Boolean composition.
How to find the area
Area formula: A = b₁·h₁ + b₂·h₂
Split the figure into basic shapes, find each area, add the joined parts and subtract the cut-outs: A = 12.48 + 14.96 = 27.44 cm².
