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

Ksivusya [100]

Answer:

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 $(x_1,y_1)$ and $(x_2,y_2)$ is given by the formula,

d = $\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Distance between Alanah and Mia = $\sqrt{(16-8)^2+(8-2)^2}$

= $\sqrt{100}$

= 10 units

Distance between Mia and Teresa = $\sqrt{(16-2)^2+(8-8)^2}$

= 14 units

Distance between Teresa and Arena = $\sqrt{(4-2)^2+(14-8)^2}$

= $\sqrt{40}$

= 6.3 units

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

= 30.3 units
