Find the distance between the following pair of points
(3, 4) and (−7, 2)
उत्तर
Distance between the points (3, 4) and (−7, 2)
= `sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2`
= `sqrt((-7 - 3)^2 + (2 - 4)^2`
= `sqrt((-10)^2 + (-2)^2`
= `sqrt(100 + 4)`
= `sqrt(104)`
= `sqrt(2 xx 2 xx 13)`
= `2sqrt(26) "units"`
