Question
Find the distance of the following point from the origin :
(8 , 15)
Solution
P = (0 , 0) , Q = (8 , 15)
PQ = `sqrt (("x"_2 - "x"_1)^2 + ("y"_2 - "y"_1)^2)`
`= sqrt ((8 - 0)^2 + (15 - 0)^2)`
`= sqrt (64 + 225)`
`= sqrt 289`
= 17 units

Using distance formula,
d(Q, R) = `sqrt(square)`
∴ d(Q, R) = `sqrt(square - 100)`
∴ d(Q, R) = `sqrt(square)`
∴ d(Q, R) = `square`
