Keywords
triangle,perimeter,distance, length, side, points
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
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
