Find the distance between the points \[\left( - \frac{8}{5}, 2 \right)\] and \[\left( \frac{2}{5}, 2 \right)\] .
उत्तर
We have to find the distance between `A ( - 8/5, 2)" and " B ( 2/5 , 2) `.
In general, the distance between A`(x_1, y_1) " and B "(x_2 , y_2) ` is given by,
`AB = sqrt((x_2 - x_1 )^2 + (y_2 - y_1)^2)`
So,
`AB = sqrt((2/5 + 8/5)^2 + (2-2)^2)`
` = sqrt(4) `
= 2
