Question

The perimeter of an equilateral triangle is 102mm. State the length of one of its sides.

Answer 1

Step-by-step explanation:

perimeter of equilateral triangle=3×side

102=3×side

then,

1102÷3=side

34 =side

Answer 2

Answer:

The length of side of equilateral triangle is 34mm

Step-by-step Explanations :

Given : perimeter of equilateral triangle = 102 mm

To find : Length of one of its side = ?

Let the length of the side of equilateral triangle be x,

We know that,

Perimeter = sum of all the sides of triangle

102 = x + x + x

102 = 3x

x = 102/3

x = 34mm

Hence, The length of side of equilateral triangle is 34mm
