Question

Area of equilateral triangle is 30 root 36 root 3 cm square find its perimeter

Answer 1

$<b > hey here is your answer$     Area of equalteral triangle =  √3/4. × a^2  = 36√3 cm^2 = a^2 = 36√3 ×4/√3 = a^2 = 144 cm^2 = a = √144 cm = a = 12 cm      The side of equalteral triangle = 12cm    Perimeter of equalteral triangle = 3×side = 3 × 12 cm  = 36 cm    Hope this helps you Please mark as brainliest answer

Answer 2

$<b >hey here is your answer$

Area of equalteral triangle =  
√3/4. × a^2  = 36√3 cm^2
= a^2 = 36√3 ×4/√3
= a^2 = 144 cm^2
= a = √144 cm
= a = 12 cm  

The side of equalteral triangle = 12cm  

Perimeter of equalteral triangle = 3×side
= 3 × 12 cm  = 36 cm  

Hope this helps you
