The distance, in units, from the school to the library and then the distance from the library to the park is 15 units.
<h3>What is the length of any line on the graph?</h3>
The distance or length of any line on the graph,
D = √{(x₂ - x₁)² + (y₂ - y₁)²}
where,
d = distance/length of the line between point 1 and 2,
(x₁ , y₁) = coordinate of point 1,
(x₂ , y₂) = coordinate of point 2,
The distance from school to the library is SL, therefore,

The distance from library to the park is LP, therefore,

Now, the distance, in units, from the school to the library and then the distance from the library to the park is 15 units (10 units + 5 units).
