6 dni temu · The precise answer is 25 × √3. To get this answer, recall the formula for the area of an equilateral triangle of side a reads area = a2 × √3 / 4. For the triangle with side 10 we obtain area = 102 × √3 / 4 = 100 × √3 / 4 = 25 × √3, which is approximately equal to 43.3.

5 dni temu · area = 0.5 × a × a × sin(60°) What is more, we know that the sine of 60° is √3/2, so the formula for equilateral triangle area is: area = (1/2) × a² × (√3 / 2) = a² × √3 / 4. The height of the equilateral triangle comes from the sine definition: h / a = sin(60°) so h = a × sin(60°) = a × √3 / 2.
Basic Formula. This is the most common formula used and is likely the first one that you have seen. For a triangle with base b b and height h h, the area A A is given by. A = \frac {1} {2} b \times h.\ _\square A = 21b×h. . Observe that this is exactly half the area of a rectangle which has the same base and height.
