Answer 1

$\huge{\overbrace{\underbrace{\mathtt{\green{ANSWER}}}}}$

Perimeter- 36cm

Step-by-step explanation:

Area of equilateral triangle = (√3)/4 (side)²

∴ (√3)/4 (side)² =36 √3

​(side)² =36×4

=9×4×4

=(4×3)²

side= 12cm

perimeter =3×side

=3×12

=36cm

Answer 2

Answer:

36 cm.

Step-by-step explanation:

Area of equilateral triangle = √3 (side)²

4

So,√3 (side)²= 36√3

4

(side)² = 36 x 4

= 9 x 4 x 4

= (4 x 3)²

Side = 12cm

Perimeter = 3 x side

= 3 x 12

= 36cm.

So Answer is 36 cm
