Question

A student starts at (0,0) and walks to (12, 0), turns and then walks to (7,12). What is the total distance that this student walked?

Answer 1

Answer:

25

Step-by-step explanation:

(0,0) to (12,0) => the distance = 12

(12,0) to(7,12) => the distance =

√[(12-0)²+(7-12)²]=√(144+5) =√169 = 13

so, the total distance = 12+13 = 25
