Answer:

Musician is the correct answer

Answer 2

Answer:

Given Perimeter =180 cm

Semi-perimeter s=2180

s=90 cm

Since all sides of equilateral triangle are equal

So,

Perimeter =180

a+a+a=180

3a=180

a=60 cm

Area of triangle =s(s−a)(s−b)(s−c)

                           =90(90−60)(90−60)(90−60)

                           =90×30×30×30

                           =(9×3×3×3)×(10)4

                           =(92)×3×(10)4

                           =9×3×(10)2

                           =9×100×3

                           =9003
