Inverted T-Beam
Inverted T-Beam: a composite plane figure made of a rectangle 7.6 × 2 cm, joined with a rectangle 2.2 × 5.2 cm. It is a classic high school (grades 9–10) geometry problem (“Structural Sections”). The net area is 26.64 cm² and the total perimeter is 29.6 cm.

How to find the area
Area formula: A = B·s₁ + s₂·h
Split the figure into basic shapes, find each area, add the joined parts and subtract the cut-outs: A = 15.2 + 11.44 = 26.64 cm².
