Question

if The Perimeter Of Equilateral Triangle Is 180cm.Then The Area Will Be​

Answer 1

Answer:

By sine formula, Area of the equilateral triangle = (a^2/2)sin 60 = (60^2/2)* sin 60 = 1558.845727 sq cm.

Answer 2

Answer:

as given,

it is an equilateral triangle

so,

perimeter of triangle = sum of all sides.

so, let the sides be a

hence, all sides are equal,

a+a+a=180cm

so, a=60cm

now,

area of eqi. triangle =√3/4×a²

=√3/4×60×60

=√3×15×60

=900√3cm²

itz your answer buddy.
