Distinguish the boundary, face and solid

Perimeter measures a boundary in units of length. Area covers a flat face in squared units, while volume fills a solid in cubed units. For a room floor, choose area; for a container's capacity, choose volume. Surface area counts the faces you would cover or paint. A circle tool takes radius or diameter, and confusing the two changes area by a factor of four. Use the labelled diagram to check what each measurement describes.

Choose the information you actually have

The right-triangle tool assumes a right angle; a general triangle solver supports other angle and side combinations. Some side-side-angle inputs produce two possible triangles, so inspect both solutions instead of choosing one silently. Coordinate tools are useful when measurements are points rather than side lengths. Convert all lengths to a consistent unit before comparing results, and remember that a mathematically exact shape may only approximate an irregular real object.
