If the square has an area of 36 sq. units, then each side is sqrt(36) or 6. This means that the common side of the triangle is 6 units. Since it is an equilateral triangle, then all three sides are 6 units, so the perimeter of the triangle is 6 * 3, or 18 units.

length of side of the square = length of side of the triangle = square root of 36 = 6 unit
the perimeter of the triangle = sum of length of the three sides = 3*6 = 18 unit

the side length of the square is 6, and perimeter of triangle is 6x3=18
