Final answer:
Without the actual line plot, we cannot determine how many squashes were 10 inches or longer. A measuring tape is the standard for measuring garden plot dimensions.
Step-by-step explanation:
The analysis of data recorded in a line plot. Considering the context, it is not about the actual measurement of a garden plot but rather about interpreting a line plot that has already been created based on the lengths of squash grown in a garden.
Unfortunately, without the actual line plot data, we cannot accurately answer the specific question about the number of squashes that were 10 inches or longer. The mention of a measuring tape is relevant as it is a common tool used for measuring lengths of garden plots or plants, but it does not directly address the student's question.
