rosijanka [135]

Given

The coordinates of the points on the path are:

P(20,7), R(-4,-9), O(20, -9), S(-4, -24)

The total length of the path from P to S is:

$=\text{ \mid PR\mid}+|RO|\text{ +}|OS|$

The distance d between two points can be found using the formula:

$d\text{ = }\sqrt{(x_2-x_1)^2\text{ +}(y_2\text{ -y}_1)^2\text{ }}$

The distance between P and R:

$\begin{gathered} |PR|\text{ = }\sqrt{(-4-20)^2\text{ +}(-9\text{ -7\rparen}^2} \\ =\text{ 28.84 units} \end{gathered}$

The distance between R and O:

$\begin{gathered} |RO|\text{ = }\sqrt{(20-(-4))^2\text{ + \lparen-9-\lparen-9\rparen\rparen}^2} \\ =\text{ 24 units} \end{gathered}$

The distance between O and S:

$undefined$
