Here are the essential concepts you must grasp in order to answer the question correctly.
Distance Formula
The distance between two points in a Cartesian plane can be calculated using the Distance Formula, which is derived from the Pythagorean theorem. The formula is given by d = √((x2 - x1)² + (y2 - y1)²), where (x1, y1) and (x2, y2) are the coordinates of the two points. This formula allows us to find the straight-line distance between any two points.

Simplified Radical Form
Simplified radical form refers to expressing a square root in its simplest terms, where the radicand (the number under the square root) has no perfect square factors other than 1. For example, √12 can be simplified to 2√3. This form is often required in mathematical answers to ensure clarity and conciseness.

Rounding Numbers
Rounding numbers involves adjusting a number to a nearby value that is simpler or more convenient, typically to a specified number of decimal places. In this context, rounding to two decimal places means keeping only two digits after the decimal point, which helps in presenting answers in a more manageable format while maintaining a reasonable level of precision.
