WebCalculating a length. The three trigonometric ratios can be used to calculate the length of a side in a right-angled triangle. Example. Calculate the length AB. WebJan 31, 2024 · To calculate the area of an equilateral triangle, you only need to know the side: area = a² × √3 / 4. Since √3 / 4 is approximately 0.433, we can formulate a quick recipe: to approximate the area of an equilateral triangle, square the side's length and then multiply by 0.433. Although we didn't make a separate calculator for the ...
