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.)

12 units

Step-by-step explanation:

The first segment, RS, is along the grid line y=4 from x=-1 to x=5, a total distance of 5-(-1)=6 grid units.

The second segment, ST, is along the grid line x=5 from y=4 to y=-2, a total distance of 4-(-2)=6 grid units.

The total length of the trail is the sum of the lengths of the first and second segments, so is 6+6=12 units.

It can help to plot the points on a graph so you can better see what it is you're being asked to find.
