- Area of an equilateral triangle formula. The formula to find the area of any triangle is: Area of a triangle = base × height 2 Area of a triangle = base × height 2. This can be shortened to: A = 1 2bh A = 1 2 b h. where b is the base length and h is the height of the triangle. Your final answer must be given in units 2. (e.g. cm 2, m 2, mm 2)

The rate of change is the derivative with respect to t so you are going to have to find a relationship between and A. The area of a triangle is half the base times the height so. A = b/2 h. From the diagram b/2 = 3.5 sin ( /2) and h = 3.5 cos ( /2). Thus. A = (3.5) 2 sin ( /2) cos ( /2)
