What is the length of B'B?

Answer 1

Its -2 and nothing else can be it

Answer 2

Answer:

5.39 units.

Step-by-step explanation:

We have been given an image of two squares on coordinate plane. We are asked to find the length of B'B.

We will use distance formula to solve our given problem.

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Let point $(0,2)=(x_1,y_1)$ and $(5,4)=(x_2,y_2)$.

Upon substituting coordinates of our given points in distance formula, we will get:

$d=\sqrt{(5-0)^2+(4-2)^2}$

$d=\sqrt{(5)^2+(2)^2}$

$d=\sqrt{25+4}$

$d=\sqrt{29}$

$d=5.3851\approx 5.39$

Therefore, the length of B'B is approximately 5.39 units.
