First find the perpendicular height (h) of the triangle using Pythagoras.
h = sqrt (102 - 52) = sqrt 75 = 8.660254038...
Now, area of a triangle = 1/2 base x height.
So: area = 1/2 x 10 x 8.660254038 = 43.3 (1 decimal place.)

The area ( A ) of an equilateral triangle with side length ( x ) can be calculated using the formula ( A = \frac{\sqrt{3}}{4} x^2 ). This formula derives from the properties of equilateral triangles and the use of basic geometric principles. Thus, if you know the side length ( x ), you can easily find the area by substituting it into the formula.
Area of an equilateral triangle is s*(sqrt 3)/2, where s is the length of a side, or: area = s * 0.866666. . .
Area = 0.5*base*height Alternatively area = 0.5*side squared*sin(60 degrees)
15.588 ft2 using the formula: (Sqrt(3)/4)×(side)²
Area of Equilateral Triangle A= S2 * (Root 3)/4, where A= Area of the triangle S= Side of the triangle.
62.354 units squared.
To get the area of an equilateral triangle, you just need to know the length of one side. Multiply the length of one side by the square root of three and then divide the product by four, and you will get the area of the triangle.

the perimeter is 36 and the area is 144
Given this area, the sides measure 52.92734 cm
You can't as there is no hypotenuse in an equilateral triangle. The hypotenuse is the side of a triangle which is opposite a right angle (90°); all angles in an equilateral triangle are 60°.

For an equilateral triangle with side length a, area = (a²√3)/4, which for a= 6cm is 15.6 cm² [rounded to 1 decimal place]
Area = side^2 x (√3)/4
Area = 15.58846 cm2
