How this service works
Area, perimeter and diagonal of a rectangle from its width and height.
Output
Returns the computed area (width × height), perimeter (2 × (width + height)), and diagonal (√(width² + height²)) of the rectangle as numeric values.
Example use cases
Flooring material estimation
“I need to figure out the area, perimeter, and diagonal of a room that's 4.5 meters wide and 6.2 meters long — can you calculate that for me?”
Fence length planning
“I'm planning a rectangular garden plot that's 10 feet wide and 15 feet long. What's the perimeter so I know how much fencing to buy, and what are the other measurements?”
Screen diagonal verification
“Can you tell me the diagonal, area, and perimeter of a rectangle that's 1920 units wide and 1080 units tall? I want to verify the aspect ratio math.”
Technical details
Endpoint
POSThttps://geometry.openverbs.com/v1/rectangleWhen to prefer
Use this endpoint when you need a quick, reliable computation of rectangle properties — area, perimeter, and diagonal — without implementing the math yourself. It is ideal for agentic workflows, educational tools, or applications that need geometry calculations as a microservice. Prefer it over the sibling circle or triangle endpoints when the shape is specifically rectangular (four right angles, two pairs of equal sides).
Side effects
- Width or height is zero or negative — the schema enforces exclusiveMinimum of 0, so invalid values will be rejected
- Missing required fields (width or height) will result in a validation error
- Non-numeric inputs for width or height will cause a schema validation failure
