Question

of the area of equilateral triangle is 36 X 1.732 cm sq. find the length of its side and parimeter.​

Answer 1

Answer:

Consider a as the length of a side of an equilateral triangle We know that Area of an equilateral triangle = (√3 × a2)/4 sq units

It is given that the area = 36√3 cm2

We can write it as (√3 × a2)/4 = 36√3

On further calculation a2 = (36√3 × 4)/ √3

So we get a2 = 36 × 4 By multiplication a2 = 144

By taking the square root a = √144 So we get a = 12 cm

By substituting the value of a Perimeter = 3a = 3 (12) = 36cm

Therefore, the perimeter of the equilateral triangle is 36cm.
