Question

the perimeter of an equilateral triangle is 2m 55cm.find the length of its side​

Answer 1

Answer:

85 cm

Step-by-step explanation:

2m 55 cm= 255 cm

In an Equilateral Triangle, there are 3 sides where all 3 have have egual length.

Perimeter= 255cm

1 side= 255/3

        = 85 cm

Answer 2

1m=100cm

therefore 2m=200cm

Perimeter of equilateral triangle= 200+55=255cm

Perimeter of equilateral triangle

=s+s+s

=3s

255 =3s

255/3 =s

85=s

Length of its side =85 cm/0.85m.
