Kudos for the right answer and explanation
Question part of the project GRE Quantitative Reasoning Daily Challenge - (2021) EDITIONGRE - Math Book If \((a, b)\) and \((c, d)\) are two points in the coordinate plane, then the distance between those two points \(= \sqrt{(c-a)^2 + (d-b)^2}\)So the distance between \((3,2)\) and \((7,5)\) \(= \sqrt{(7-3)^2 + (5-2)^2}\)
\(= \sqrt{(4)^2 + (3)^2}\)
\(= \sqrt{16 + 9}\)
\(= \sqrt{25}\)
\(= 5\)
Answer: A
