How many total blocks will she travel if she goes to Amanda‘s house and then to Karen’s and finally back home

Now, to find Karen to own place, we have to use the Pythaogrean Theorem. It is applicable for right triangle (which is shown, Amanda's place is the right angle).

The two distance we found are the two legs of the triangle and the other side (what we need to find) is the hypotenuse (which is the side opposite of right angle). The theorem says:

Leg^2 + Another Leg^2 = Hypotenuse^2

We know the 2 legs' length, so we can solve for hypotenuse (Karen to Own place Distance). Shown below:

[tex]5^2 + 6 ^ 2 \\=25+36\\=61[/tex]

So, we have:

Hypotenuse^2 = 61

Hypotenuse = Sqrt(61) = 7.81

Rounded to nearest block, that is 8 blocks

So, total distance traveled is:

5 + 6 + 8 = 19 blocks
