Question

Find the distance between C(2,4) and D (5. 7). Round to the nearest tenth, if necessary?
​

Answer 1

The answer 4.2 units

Explanation:

The distance between two points can be found by using the formula

`d = \sqrt{ ({x1 - x2})^(2) + ({y1 - y2})^(2) } \\`

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

C(2,4) and D (5. 7)

We have

`|CD| = \sqrt{ ({2 - 5})^(2) + ({4 - 7})^(2) } \\ = \sqrt{ ({ - 3})^(2) + ( { - 3})^(2) } \\ = √(9 + 9) \\ = √(18) \: \: \: \: \: \\ = 3 √(2) \: \: \: \: \: \\ = 4.242640687...`

We have the final answer as

4.2 units to the nearest tenth

Hope this helps you
