Chapter 8: Q29. (page 415)

Find the distance between the pair of points with the given coordinates $(2.3, - 1.2) and (- 4.5, 3.7)$ .

Short Answer

Expert verified

The distance between the given pair of points is $8.38 units$ .

Step by step solution

Step 1. Write down the given information.

The given pair of points have coordinates $(2.3, - 1.2) and (- 4.5, 3.7)$ .

Step 2. Concept used.

If a line segment has end-points at $(x_{1}, y_{1}) and (x_{2}, y_{2})$ then the distance $(d)$ between these points is given as:

$|d| = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2}} . . . . (1)$

Step 3. Calculation.

The distance $(d)$ between the pair of points with given coordinates $(2.3, - 1.2) and (- 4.5, 3.7)$ is evaluated using the formula (1) stated above.

\begin{matrix} |d| = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2}} \\ = \sqrt{{(- 4.5 - 2.3)}^{2} + {(3.7 + 1.2)}^{2}} \\ = \sqrt{{(- 6.8)}^{2} + {(4.9)}^{2}} \\ = 8.38 units .... (Approx.) \end{matrix}

Step 4. Conclusion.

The distance between the given pair of points is $8.38 u n i t s$ .
