Best ResponseYou've already chosen the best response.1If the area of the square is 81, then a side of the square is 9. The perimeter of the square is 4*9 = 36. The equilateral triangle would have side length of 12. dw:1347692722838:dw The area of the equilateral triangle is 1/2 b times height. The height is found by using the 306090 theorem. You can also use the specialty theorem for the area of an equilateral triangle. That is the square of a side times the square root of 3 all divided by 4.
