Answer:
The total length (in units) of the biking trail is 17 units.
Step-by-step explanation:
o find distance between points A(x¹, y¹) and B(x², y²), we use formula:
The trail starts at P(−2, 2) and goes to Q(5, 2).
So, the distance PQ will be calculated as:
PQ = 7 units
Then the trail goes from Q(5, 2) to R(5, −5).
So, the distance QR will be calculated as:
QR = 7 units
And then from R(5, −5) to S(8, −5).
QR = 3 units
Hence, the total length of the biking trail is:
PQ + QR + QR = 7 + 7 + 3 = 17 units
