👉 Crescents, also known as "squares," are a common geometric figure in mathematics and architecture. They can be thought of as small squares with their sides being perpendicular to each other. The area of a crescent is calculated by multiplying its length (the side) times its width (half the length). For example, if we have a crescent shape that is 5 units long and 3 units wide, its area would be: Area = Length x Width = 5
