Geometric Pine
Geometric Pine: a composite plane figure made of a trapezoid with bases 6.8 and 3.2 cm and height 3.2 cm, joined with a triangle with base 5 cm and height 3.2 cm, joined with a rectangle 1.8 × 2.4 cm. It is a classic primary school geometry problem (“Additive Figures”). The net area is 28.32 cm² and the total perimeter is 28.86 cm.

Area of each basic shape before the Boolean composition.
How to find the area
Area formula: A = A_trap + A_tri + A_rett
Split the figure into basic shapes, find each area, add the joined parts and subtract the cut-outs: A = 16 + 8 + 4.32 = 28.32 cm².
