Question

Find the distance between the points (13, 20) and (18, 8).

Answer 1

distance = sqrt (13-18)^2 + (20-8)^2 )

= sqrt ( 5^2 + 12^2)

= sqrt 169 = 13

Answer 2

Answer: 13 units

Explanation:

The distance formula to calculate distance between two points (a,b) and (c,d) is given by :-

`d=√((d-b)^2+(c-a)^2)`

Given points : (13, 20) and (18, 8)

Now, the distance between the points (13, 20) and (18, 8)is given by ;-

`d=√((8-20)^2+(18-13)^2)\\\\\Rightarrow\ d=√((-12)^2+(5)^2)\\\\\Rightarrow\ d=√(144+25)\\\\\Rightarrow\ d=√(169)\\\\\Rightarrow\ d=13\text{units}`

Hence, the distance between the points (13, 20) and (18, 8) is 13 units.
