Question

I WILL GIVE INSTANT BRANLEST FOR WHO ANSERS THIS QUESTION CORECTLY The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−1, 4) and goes to S(5, 4) and continues to T(5, −2). The total length of the walking trail is ____ units. (Input whole numbers only.)

Answer 1

I believe it is 12 since it is not asking for shortest distance

Answer 2

Draw the trail and label all the points on the triangle.

Then, use the distance formula between points: 

Distance = $\sqrt{(x1-x2)^2 + (y1-y2)^2}$
