Question

the square of an equilareral triangle is
$36 \sqrt{3}$
sq cm find its perimetre

Answer 1

I guess it's area.
Area of eq. ∆ = 36√3
WKT, Area of eq ∆ = [√3/4] side^2
Therefore, (√3/4)side^2=36√3
This implies, side = √144 = 12 cm
Therfore, Perimeter = 3×12 = 36 cm.

Answer 2

Hey mate......^_^

Here's ur ans. ⬇


_________________


Area of equilateral triangle = √3 a^2 /4

36√3 = √3 a^2/4

36 ×4= a^2

a = 12 m

Therefore ,side of equilateral triangle = 12 m


Perimeter = Sum of all sides

= 3×12

= 36 m
