Question

if the perimeter of an equilateral triangle is 60cm then what it is area​

Answer 1

Step-by-step explanation:

Perimeter = 60cm

1 side = 60/3 = 20 cm

√s(s-a)(s-b)(s-c)s(s−a)(s−b)(s−c)

s = 30

√30(30-20)(30-20)(30-20)

=√30×10×10×10=√30000cm² = 100√3 cm²

mark me brainlest ☺️ plzzzzzzz

Answer 2

perimeter= 3*side

60= 3*side

side= 20cm

area= √3/4a^2

= √3/4*20= 5√3 ( answer)
