Question

the area of an equilateral triangle is 16 root3. find its perimeter

Answer 1

Area of an equilateral triangle = √3/4 a2 units Given area of the triangle is 16√3 cm2 √3/4 a2 =16√3 cm2 = a2 = 16√3 cm2* 4/√3 = a2 = 64 cm2 = a = 8 cm Perimeter of the triangle = 3a = 3*8cm = 24 cm

Answer 2

Area of an equilateral triangle  √3/4 a² units
given are of the triangle is 16 √3 cm²
√3/4 a² = 16 √3 cm²
=a² =  16 √3 cm² *4/√3
=a² = 64cm²
=a = 8cm
perimeter of the triangle = 3a = 3*8cm = 24cm
