Answer 1

Answer:

a=4

Step-by-step explanation:

by the theorem ,

root 3 a square by 4

we the answer ie,a =4

Answer 2

Solution :

Let the side of the equilateral triangle

is ' a ' .

Area of the equilateral triangle (A) = 4√3

=> ( √3/4 )×a² = 4√3

=> a² = 4√3 × ( 4/√3)

=> a² = 16

=> a = √16

=> a = 4 units

Perimeter of the triangle = 3a

= 3 × 4 units

= 12 units
