Step-by-step explanation:
A line of poetry made up of five metrical feet is called Pentameter. Pentameter is a style of poetic meter in which there are five sets of iambs (or ten syllables) per line of poem. Each iamb consists of an unstressed and a stressed syllable. For example, the line 'The curfew tolls the knell of parting day' is an example of iambic pentameter because it has five iambs.
