area=1/2 times base times height base=side draw a line down the middle of te tiangle so you get 2 right triangles side by side 1/2base is one leg base is hypotonuse height is unknown equilateral means that it is a 30-60-90 triangle with hypotonuse equal to 2x, height=x√3, bottom is x 1/2 times base times height=1959 1/2 times x times x√3=1959 multiply both sides by 2 (x^2)√3=3918 divide both sides by √3 x^2=3918/√3 square root both sides x=47.5611 side=hypotonuse=2x 2x=2*47.5611 side=95.12222
