Question 328949
The side of an equilateral triangle is 4 inches shorter than the side of a square. The perimeter of the square is 38 inches more than the perimeter of the triangle. Find the length of the side of the square. 
-----------
Let a side of the square be "s".
Its perimeter = "4s".
-----
A side of the equilateral triangle is "s-4"
Its perimeter = 3(s-4) = 3s-12
------------------------------------
Equation:
Perimeter of square - Perimeter of Equilater Triangle = 38
4s - (3s-12) = 38
s = 26 inches (length of a side of the square)
