Assuming that you want to find the area of an equilateral triangle using the formula for a triangle, but without finding or using the height is impossible. An everyday use of triangle math is if you want to lay tiles at perfect 90° or 45° to the sides of a room. What is the area of a 45-45-90 triangle, with a hypotenuse of 8mm in length? In an equilateral triangle, since all #3# sides have the same length, and the angles within the triangle are equal, this means that half of the side length will equal to the length of the base if the triangle were split into #2# halves.
then divide by 1/2.
Now in order to find the area of the triangle we need to calculate its height. This is a straightforward application of the side and height rule which calls for a simple multiplication of the two, and then a division by two.
Here is a visual representation as to what the triangle would look like (focus on the angles): Once you have found the height, substitute the values for base and height into the following formula to solve for the area: Let us consider the equilateral triangle in the figure below. often use triangular support. Again a number puzzle. c = hypotenuse. How do you find the area of the trapezoid below? https://www.gigacalculator.com/calculators/area-of-triangle-calculator.php.
