Answer:
The total length (in units) of the biking trail is 15 units
Step-by-step explanation:
Given:
P = (-2,1)
Q = (6, 1)
R = (6,-3)
s = (9,-3)
To Find:
The total length (in units) of the biking trail = ?
Solution:
Distance between two points can be found by the
d = --------------(1)
Step 1: Distance between PQ
Here
Substituting the values in eq(1)
PQ =
PQ =
PQ =
PQ = 8
Step 2: Distance between QR
Here
Substituting the values in eq(1)
QR =
QR =
QR =
QR = 4
Step 3: Distance between RS
Here
Substituting the values in eq(1)
RS=
RS =
RS =
RS = 3
Step 4: Finding the total distance of the trail
The total distance of the biking trail is = PQ + QR + RS
=> 8+4+3
=> 15
