Question

"Find the distance between P (1,2) and Q (4.5, 10.75)

Answer 1

Answer:

Step-by-step explanation:

Use distance formula.

(1 , 2)  Q(4.5, 10.75)

Distance = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

              $= \sqrt{(4.5-1)^{2}+(10.75-2)^{2}} \\\\\\=\sqrt{(3.5)^{2}+(8.75)^{2}} \\\\= \sqrt{12.25+76.5625} \\\\= \sqrt{88.8125}\\\\= 9.42 units$
