Rational numbers are numbers that can be written as the fraction of two integers. To multiply rational numbers together, simply the problem, then you multiply the tops and the bottoms separately to get your answer.

we know that
The <u>perimeter</u> of a<u> triangle</u> is the sum of the three <u>length</u> <u>side</u>
To find the<u> length</u> <u>side</u> calculate the <u>distance</u> between two <u>points</u>
The formula to calculate the <u>distance</u> between to <u>points</u> is equal to
![d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28y2-y1%29%5E%7B2%7D%2B%28x2-x1%29%5E%7B2%7D%7D)
Step 1
Find the <u>distance</u> ZY
substitute the values
![d=\sqrt{(1-0)^{2}+(3-1)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%281-0%29%5E%7B2%7D%2B%283-1%29%5E%7B2%7D%7D)
![dZY=\sqrt{5}\ units](https://tex.z-dn.net/?f=dZY%3D%5Csqrt%7B5%7D%5C%20units)
Step 2
Find the <u>distance</u> XY
substitute the values
![d=\sqrt{(1-4)^{2}+(3+1)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%281-4%29%5E%7B2%7D%2B%283%2B1%29%5E%7B2%7D%7D)
Step 3
Find the <u>perimeter</u> of the <u>triangle</u>
![P=ZX+ZY+XY](https://tex.z-dn.net/?f=P%3DZX%2BZY%2BXY)
we have
![dZX=2\sqrt{5}\ units](https://tex.z-dn.net/?f=dZX%3D2%5Csqrt%7B5%7D%5C%20units)
![dZY=\sqrt{5}\ units](https://tex.z-dn.net/?f=dZY%3D%5Csqrt%7B5%7D%5C%20units)
Substitute
![P=(2\sqrt{5}+\sqrt{5}+5)\ units](https://tex.z-dn.net/?f=P%3D%282%5Csqrt%7B5%7D%2B%5Csqrt%7B5%7D%2B5%29%5C%20units)
therefore
the answer is
![P=(3\sqrt{5}+5)\ units](https://tex.z-dn.net/?f=P%3D%283%5Csqrt%7B5%7D%2B5%29%5C%20units)
