Question

Find the distance between points a and point b
a (8,1) b (4,9)​

Answer 1

Required Answer:-

• A (8,1)
• B (4,9)

use distance formula

`\qquad\quad {:}\longmapsto\sf AB=√((x_2-x_1)^2+(y_2-y_1)^2)`

`\qquad\quad {:}\longmapsto\sf \sqrt {(4-8)^2+(9-1)^2}`

`\qquad\quad {:}\longmapsto\sf √((-4)^2+(8)^2)`

`\qquad\quad {:}\longmapsto\sf \sqrt {16+64}`

`\qquad\quad {:}\longmapsto\sf \sqrt {80}`

`\qquad\quad {:}\longmapsto\sf AB=4√(5) \:or \:8.94`
