Question

if the area of equilateral triangle is 36√3 cm2 find its perimeter​

Answer 1

Answer:

√3/4 a^2 = 36√3

then a = √144 = 12

then the perimeter = 4×12 = 48 CM answer

Answer 2

Answer:

Area of equilateral triangle =

$\frac{ \sqrt{3} }{4} {a}^{2} = 36 \sqrt{3 } \\ \implies{a}^{2} = 36 \times 4 \\ \implies a = \sqrt{36 \times 4} = 6 \times 2 = 12 \: cm$

So parameter will be 12 × 3 = 36 cm
