Raj runs in a park which is in a shape of rectangle, he completes one lap and then he runs across the diagonal of the park. The dimensions of the park are 100 m × 120 m. What is the total distance travelled by him diagonally?

A diagonal is a line that connects two vertices of a polygon or a solid, whose vertices are not on the same edge.

Generally, a diagonal is defined as a sloping line or the slant line, that connects to the vertices of a shape. Diagonals are defined as lateral shapes that have sides/edges and corners.
