Alanah is picking up two friends to go to a concert. She drives from her house to pick up Mia, then she drives to pick up Teresa, and then they go to the arena to see the concert. Answer the questions to find the total distance of Alanah's trip to the arena. When necessary, round answers to the nearest tenth.

Total distance = 30.3 units

Step-by-step explanation:

Coordinates for the location of Alanah, Mia, Teresa and Arena are,

Alanah → (2, 8)

Mia → (8, 16)

Teresa → (8, 2)

Arena → (14, 4)

Distance between two points and is given by the formula,

d =

Distance between Alanah and Mia =

                                                          =

                                                          = 10 units

Distance between Mia and Teresa =

                                                          = 14 units

Distance between Teresa and Arena =

                                                              =

                                                              = 6.3 units

Total distance of Alanah's trip to Arena = 10 + 14 + 6.3

                                                                  = 30.3 units
