Question

If the area of an equilateral triangle is 16 root 3 cm square Then Find perimeter

Answer 1

we know that area of a equilateral triangle is root 3 by 4 so .....

Answer 2

$area = 16 \sqrt{3} \\ \sqrt{3} \div 4 {a}^{2} = 16 \sqrt{3} \\ {a }^{2} = 64 \\ a = 8cm \\ perimeter = a + a + a = 8 + 8 + 8 = 24cm$
