Symmetric H-Shape
Symmetric H-Shape: a composite plane figure made of a rectangle 6.8 × 7.2 cm, minus a rectangle 2.8 × 2.4 cm, minus a rectangle 2.8 × 2.4 cm. It is a classic primary school geometry problem (“Frames & Cutouts”). The net area is 35.52 cm² and the total perimeter is 37.6 cm.

Area of each basic shape before the Boolean composition.
How to find the area
Area formula: A = B·H − 2·(b·h)
Split the figure into basic shapes, find each area, add the joined parts and subtract the cut-outs: A = 48.96 − 6.72 − 6.72 = 35.52 cm².
