An equilateral triangle has a side length of 30 meters. Determine the area of the triangle
.
Area of any triangle is (1/2)bh
.
calculating height:
let h = height
h^2 + 15^2 = 30^2
h^2 = 30^2 - 15^2
h^2 = 675
h = sqrt(675)
h = 25.981 meters
.
area = (1/2)bh
area = (1/2)(30)(25.981)
area = 389.71 square meters
