If two figures, an equilateral triangle (side t) an a square (side s) have the same area, what is the ratio t:s?

area of trig = 0.5 * b * h

where $$b = t$$and $$h = \frac{\sqrt{3}t}{2}$$

therefore area of the trig = $$\frac{\sqrt{3}t^2}{4}= s^2$$

therefore $$\frac{t}{s}= \frac{2}{{3}^{\frac{1}{4}}$$
