Question

What is the distance between `(7, 4)` and #(10, 8) #?

Answer 1

`d = 5` units

Explanation:

Distance =`sqrt((x_2-x_1)^2 + (y_2-y_1)^2`
Here, `x_2` is 10,
`x_1` is 7,
`y_2` is 8,
`y_1` is 4.

Substituting and solving we get:
`d = sqrt((10-7)^2 + (8-4)^2`
`d = sqrt(3^2 + 4^2)`
`d = sqrt(9+ 16)`
`d = sqrt(25)`
`d = 5` units
