Question 655636
They should have asked Laverne and Shirley.  All the sides of an equilateral triangle are the same.<P>
Call Squiggy's sides x and Lenny's sides x+10.  The perimeter of S's triangle is 3x and the perimeter of L's triangle is 3(x+10) = 3x + 30.<P>
The sum of the perimeters is 3x + 3x +30 = 186 (solve for x)<P>
6x = 156 and x = 26.<P>
S's triangle has sides of 26 for a perimeter of 78.  L's triangle has sides of x+10 = 36 and a perimeter of 108.<P>
