Answer:
And summer's lease hath all too short a date
Nor lose possession of that fair thou ow'st
Explanation:
Iambic pentameter is a form of poetical writing style where there are ten syllables/ iambs / meters in a line. These words in each line will also be an alternation between an unstressed and a stressed syllable.
Among the lines given in the question, the last two lines are written in an iambic pentameter form. The lines are from William Shakespeare's "<em>Sonnet 18</em>",
And <u>sum</u>mer's<u> lease</u> hath<u> all</u> too <u>short</u> a <u>date
</u>
Nor<u> lose</u> po<u>sses</u>sion <u>of</u> that<u> fair</u> thou <u>ow'st</u>
The stressed words are underlined, thus the evident alternating unstressed and stressed meter form. Thus, these two lines are written in an iambic pentameter form.
