Warning: I suspect there is something wrong in the statement of this question; however....

If the perimeter of an equilateral triangle is 36 inches, each side is 12 inches and by the Pythagorean Theorem the height is sqrt(12^2-6^2) = sqrt(108) = 6sqrt(3)

The area of the triangle is
A = 1/2bh

= 1/2*12*6sqrt(3) "square inches"

= 36sqrt(3) "square inches"
