Question

Find the distance between the two points (9, 3) and (21, 23)

Answer 1

`{ \red{ \boxed{ \sf{ √(344) \: units}}}}`

Explanation:

Let, (9, 3) = (x1, y1) and (21, 23) = (x2, y2)

By using distance formula, we can find the answer. Let us use the formula and get answer fast.

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

Substitute all the values in this above formula.

`{ \sf{d = \sqrt{ {(21 - 9)}^(2) + {(23 - 3)}^(2) }}}`

`{ \sf{d = \sqrt{ {(12)}^(2) + {(20)}^(2) }}}`

`{ \sf{d = √(144 + 200)}}`

`{ \sf{d = √(344) \: units}}`
