Question

03
The perimeter of an equilateral triangle is 23.4 cm. Find its side length.​

Answer 1

Answer:

we know that

Perimeter of a equilateral triangle = sum of all sides

Given

perimeter = 23.4

1st side = ?

2nd side = ?

3rd side = ?

let it be x

To find

23.4 = x+x+x

23.4 = 3x

x= 23.4/3

x = 7.8

therefore 1st side 2nd side and 3rd side is 7.8cm

as it is a equilateral triangle

Answer 2

Answer:

7.8cm

Step-by-step explanation:

the perimeter of an equilateral triangle = 3a

                             (where a is the length of the side of triangle)

according to question,

3a = 23.4cm

 a  = 7.8cm

therefore sidelength of triangle = 7.8 cm
