Question

Calculate the area and the height of an equilateral triangle whose perimeter is 60 cm.

KnowledgeBoat · Accepted Answer

Given: Perimeter = 60 cm Let the length of each side of an equilateral triangle be 'a' cm. Perimeter = Sum of all sides ⇒ 60 = a + a + a ⇒ 60 = 3a ⇒ a = = 20 cm. By formula, Hence, the area of triangle = 173.2 cm2 and the height = 17.32 cm.
