The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to S(3, 4) and continues to T(3, −1). The total length of the walking trail is ___

The total length will be "10 units". A further explanation is given below.

Explanation:

The given points are:

R(−2, 4)

S(3, 4)

T(3, −1)
