Which Mechanical paper size has an approximate drawing area of 20 X 15?

The correct choice reflects that Mechanical C paper size is designed to provide an approximate drawing area of 20 inches by 15 inches. This size is commonly used for architectural and engineering drawings because it offers sufficient space for detailed designs while remaining manageable.

Mechanical C, typically sized at 18 inches by 24 inches, provides a generous drawing area that allows for clear and comprehensive representation of technical details and dimensions. The proportions of this size are ideal for creating precise schematics, which is crucial in the fields of engineering and architecture.

Understanding the specifics of mechanical paper sizes is essential, as different sizes serve various purposes and fit different types of projects and requirements. While the other sizes mentioned may vary in terms of their measurements and usages, they do not approximate the specific drawing area of 20 by 15 inches as precisely as Mechanical C does.
