Question

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

Answer 1

Answer:

Length of a side of the equilateral triangle = 85 cm

Step-by-step explanation:

Given :

Perimeter of the equilateral triangle = 2 m 55

To find :

The length of a side of the equilateral triangle

Taken :

First each side of the equilateral triangle are same

So , find the length of its side use this formula -:

$\boxed{\sf{S=\dfrac{P}{N}}}$

Where,

S = Length of a side of the equilateral triangle

P = Perimeter of the equilateral triangle

N = Number of sides in a triangle

Solution :

First convert m into cm

So , 1 m = 100 cm

Then 2m 55cm -:

= (2×100)+55cm

= 200cm+55cm

=255cm

$:\implies\sf{S=\cancel{\dfrac{255cm}{3}}}$

$:\implies\sf{S=85cm}$

So , the length of a side of the equilateral triangle is 85 cm .

Answer 2

Step-by-step explanation:

Perimeter of equilateral triangle = 2 m 55 cm= (2×100)+55 cm=255 cm

Side of EQUILATERAL triangle = 255/3=85 cm.
