Length =  \sqrt{(Y_2-Y_1)^2 + (X_2-X_1)^2}

Point \ (4, 2) \ and \ (8, 5)

Length =  \sqrt{(5-2)^2 + (8-4)^2}

Length =  \sqrt{(3)^2 + (4)^2}

Length =  \sqrt{9  + 16}

Length = \sqrt{25}

Length = 5

\ Answer \Longrightarrow \boxed {\boxed {Length = 5}}

Find the area of the figure.
Alenkinab [10]

Answer:

24 units

Step-by-step explanation:

In this problem, the area of this shape is measured in units.

1 unit = 1 little square

So, lets count all of the full squares. There are 20 of them.

Now lets count all of the half squares. There are 8 half squares.

Now, if we divide 8 over 2, we get 4 full units.

Now we just add up the units: 20 + 4 = 24 units

Hope this helps!
