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.) numerical answers expected! answer for blank 1:

Length of the walking trail is 12 units.

Explanation:

Three points of the walking trail are R(-1,4),S(5,4)and T(5,-2). so we have to calculate the distance between points R and S and also between S and T. finding the sum of these distances would give the distance of the walking trail.

The equation to calculate the distance between two points and is  

RS=  

=

ST=  

=

length of the walking trail = RS+ST= 6+6 =12
