Answer 2

Answer:

17.32 sq.cm (Approx)

Step-by-step explanation:

Perimeter of equilateral triangle=60 cm

So length of each side= 60/3 cm

                                     =20 cm

So area=(√3)/4*side^2                    [Pronounce ^ as to the power of]

            =(√3)/4*20^2 sq.cm

            =(√3)/4*40 sq.cm

            =(√3)*10 sq.cm

            =17.32 sq.cm                   [Note:- The answer is a approximated result]

Ans:-The area of the equilateral triangle is 17.32 sq.cm.(Approx)
