What is the length of the segment joining (1,2) and (4,6)?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 5.
Distance between (1, 2) and (4, 6) = √[(x2 – x1)2 + (y2 – y1)2]
Here, x1 = 1, x2 = 4, and y1 = 2, y2 = 6
= √[(4 – 1)2 + (6 – 2)2]
= √(32 + 42)
= √(9 + 16)
= √25
= 5 cm
