Option A:
Yes, he is correct.
Solution:
To find the distance between two points (2, 4) and (6, 3).
Distance between two points formula:
![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
Here ![x_1=2, x_2=6, y_1=4, y_2=3](https://tex.z-dn.net/?f=x_1%3D2%2C%20x_2%3D6%2C%20y_1%3D4%2C%20y_2%3D3)
Substitute these in the distance formula.
Step 1:
![d=\sqrt{(6-2)^2+(3-4)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%286-2%29%5E2%2B%283-4%29%5E2%7D)
Step 2 :
Using BODMAS rule, first simplify the values into the bracket.
![d=\sqrt{(4)^2+(-1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%284%29%5E2%2B%28-1%29%5E2%7D)
Step 3:
Squaring the numbers.
![d=\sqrt{16+1}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B16%2B1%7D)
![d=\sqrt{17}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B17%7D)
Therefore, George's work is correct.
