Question

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

Answer 1

Answer:

Well if the perimeter is 60cm and all sides are equal then each side is 20cm. This would mean that a line representing the height of the triangle will bisect the far side, giving us 2 triangles with 20cm hypotenuses and one side of 10cm and 1 shared side representing the height
