Question

equilateral triangle is 16 under root 3 metre square find its perimeter

Answer 1

area of equilateral triangle = √3/4 side square
16√3 = √3/4 side square
side square = 64
side =√64
side = 8
now perimeter = 3 side = 3* 8 = 24

Answer 2

Answer:

Step-by-step explanation:

Area of equi triangle = √3side^2 ÷ 4

16√3 = √3a^2 ÷ 4

16 = a^2 ÷ 4

16 × 4 = a^2

64 = a^2

√64 = a

Side of equi triangle = 8

Perimeter = 8 + 8 + 8

Perimeter = 24
