Question

Find the distance between the two points rounding to the nearest tenth (if necessary).

(3,6) and (1,8)

Answer 1

2.8 units

Explanation:

`d = \sqrt{ {(3 - 1)}^(2) + {(6 - 8)}^(2) } \\ \\ d = \sqrt{ {(2)}^(2) + {( - 2)}^(2) } \\ \\ d = √(4 + 4) \\ \\ d = √(8) \\ \\ d = 2.82842712 \\ \\ d \approx \: 2.8 \: units`
