Question

Find the distance between the points (11, 4) and (10, 5).

Answer 1

√(x1-x2)²+(y1-y2)²
√(11-10)²+(4-5)²
√1²+(-1)²
√1+1
∴√2

Answer 2

Answer:

The distance is √2 unit.

Step-by-step explanation:

By the distance formula,

The distance between $(x_1,y_1)$ and $(x_2, y_2)$ is,

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Hence, the distance between the points (11, 4) and (10, 5) would be,

$d=\sqrt{(10-11)^2+(5-4)^2}$

$=\sqrt{(-1)^2+(1)^2}$

$=\sqrt{1+1}$

$=\sqrt{2}\text{ unit}$
