Measures are defined in the presentation layer.

False
Measures are defined in the Business Model and Mapping layer of the repository, not the Presentation layer. The Presentation layer only handles how measures are displayed to end users with friendly names and organizational structure. The actual measure definitions, aggregation rules, and calculations are configured in the BMM layer.
Measures (numeric, aggregatable facts like sales or revenue) are defined in the Business Model and Mapping layer of a BI semantic model, where calculations and aggregation rules are specified. The presentation layer only controls how those already-defined objects are organized, labeled, and exposed to end users in folders/subject areas, so the statement is false.
