Havent done this in years but i think it would just be 12
To find the perimeter<span> of a polygon, take the sum of the length of each side. The formula for </span>perimeter<span> of a triangle would be the sum of the three side lengths (a +b+c). In the case, where it is a regular polygon, the perimeter would be 3 times the side length. Hope this answers the question.</span>
4:7=m:42
7*6=42
so multiply 4*6 also and m=24
or 4:7=24:42
The correct answer is Y=2
