Bowtie Double Sector
Bowtie Double Sector: a composite plane figure made of a circular sector of radius 4.2 cm and angle 90°, joined with a circular sector of radius 4.2 cm and angle 90°. It is a classic high school (grades 9–10) geometry problem (“Sectors & Annuli”). The net area is 27.69 cm² and the total perimeter is 29.99 cm.

Area of each basic shape before the Boolean composition.
How to find the area
Area formula: A = ½·π·R² · 2p = 4R + πR
Split the figure into basic shapes, find each area, add the joined parts and subtract the cut-outs: A = 13.85 + 13.85 = 27.69 cm².
