Question

find the length of side of an equilateral triangle having perimeter 29.9 cm​

Answer 1

SOLUTION ☺️

Given,

perimeter = 29.9cm

So, we know that perimeter of equilateral triangle = 3a

=) P= 3a

=) 29.9= 3a

=) a= 29.9/3

=)a= 9.966 cm

Answer 2

Answer:

The side of an equilateral triangle is 9.97 cm .

Step-by-step explanation:

Given information,

Perimeter of equilateral triangle is 29.9 cm.

We have to find out the side of an equilateral triangle.

Equilateral triangle means the triangle which is having all equal sides.

By finding the length of one side we can find out the length all sides.

As we know that,

The perimeter of equilateral triangle = 3S

Where,

S is the side of an equilateral triangle.

By putting given values in the formula

29.9 = 3 S

$S = \frac{29.9}{3}$

S = 9.97

Hence,

The side of an equilateral triangle is 9.97 cm .
