#12 The distance between the points (3, 3) and (7, 3) is

Marina CMI [18]

Solution:

We have been asked to find the distance between the points (3, 3) and (7, 3).

we can find the distance between the two points using the distance formula.

The distance formula is given as

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \\ \text{where } (x_1, y_1) \ and \ (x_2, y_2) \ are \ two \ points\\$

Now substitute the given values we get

$D=\sqrt{(7-3)^2+(3-3)^2}\\ \\ \ D=\sqrt{4^2+0}=4\\$

Hence the distance between the given points is 4
