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

Step 1
Find the <u>distance</u> ZY
substitute the values


Step 2
Find the <u>distance</u> XY
substitute the values

Step 3
Find the <u>perimeter</u> of the <u>triangle</u>

we have


Substitute

therefore
the answer is

So the ratio is 100:60 and that simplified is 5:3. for every 5 blue there is 3 red
1.70 - 0.45 = 1.25
1500 ÷ 1.25 = 1200
