Question

If point C has coordinates (4, 2) and point D has coordinates (8, 5), then what is the length of CD?

Answer 1

`Length = √((Y_2-Y_1)^2 + (X_2-X_1)^2)`


`Point \ (4, 2) \ and \ (8, 5)`


`Length = √((5-2)^2 + (8-4)^2)`


`Length = √((3)^2 + (4)^2)`


`Length = √(9 + 16)`


`Length = √(25)`


`Length = 5`


`\ Answer \Longrightarrow \boxed {\boxed {Length = 5}}`
