Question

Find the side and height of an equilateral triangle whose area is 100 root 3

Answer 1

Answer:

Area = √3/4 a², where a is the side of triangle.

Given area = 100√3

=> 100√3 = √3/4 × a²

=> a² = 100×4

=> a = 20

Hence, the side of equilateral triangle is 20.

Height of triangle = √300 = 17.32
