How do you find the area of equal lateral triangle? - Answers

Simply, if you know the height of the triangle, that is the length from an angle to an opposite base, a line that is an altitude of the triangle, then you could find the area using the simple formula for area of any triangle, which is 0.5(base*height) * being multiply of course. A diagram: ^ /|\ / | \ / | \ / |h \ /__|__\ b That bottom line labeled 'b' is base and that altitude labeled 'h' is height. If the height is not readily available, then the alternative formula just for equilateral triangles is (assuming that s is the length of one side) [s2*squareroot(3)]/4 or in English parentheses side squared times the square root of 3, end parentheses over 4.
