Find the area of an equilateral triangle with apothem of 5cm.
Pani-rosa [81]

Answer:

16.64645cm²

Step-by-step explanation:

All of the angles are equal: A = B = C = 180/3 = 60°.

All of the sides are equal: a = b = c.

h = 5 cm, sin60 = h/a = 5/a, a = 5/sin60 = 5.77 cm.

Area = 1/2bh = 1/2 x 5.77 x 5.77 = 33.2929/2 = 16.64645cm²
