Square Frame
Square Frame: a composite plane figure made of a square with side 6.8 cm, minus a square with side 3.8 cm. It is a classic primary school geometry problem (“Frames & Cutouts”). The net area is 31.8 cm² and the total perimeter is 42.4 cm, including 15.2 cm along the inner hole.

Area of each basic shape before the Boolean composition.
How to find the area
Area formula: A = L² − l²
Split the figure into basic shapes, find each area, add the joined parts and subtract the cut-outs: A = 46.24 − 14.44 = 31.8 cm².
