Answer 1

Answer:we know the are of equilateral triangle is root 3/ 4 * a2

a is the sides of the equilateral triangle

so putting the values. :

root 3 / 4 * a2  = root 3

root 3 gets cancelled.

1/4 * a2 = 1

a2 = 4

a = 2

the length of all sides of the triangle is 2 cm as it is given it is equilateral triangle
