Ahhh OK

yep

anonymous · Answer

It says that the perimeter of an equilateral triangle is 12a+18b 
So all sides are equal. U can take 3 as the common term. 
3( 4a+6b) Then a side will be 4a+6b...

Becauz it's an equilateral triangle all sides are equal...
Now u can use the Pythagoras Theorem to find the mid-segment of the triangle..:)
