Answer :

Area of an Equilateral Triangle =

where a represents the length of sides

Given Area of Equilateral Triangle 121√3 cm2


a2 = 121 × 4

a = 11 × 2

a = 22 cm

Perimeter of the triangle = 22 × 3 = 66 cm.

Since the full wire is made into a circle

Circumference of the circle = 66 cm.

Let Radius of the circle be r
we know, circumference of a circle = 2πr

r = 10.5 cm

Area of circle =

Answer: Area of Circle = 346.5 cm2
