Question

The perimeter of an equilateral triangle is 14.4 cm. Find out the length of the side of that triangle in decimal fraction.​

Answer 1

4.8 cm

Explanation:

Given,

Perimeter of an equilateral triangle = 14.4 cm

As we know,

Perimeter of an equilateral triangle = 3 × sides (s) = 3s

Therefore,

By the problem,

=> 3s = 14.4 cm

• [On dividing both sides with 3]

`= > (3s)/(3) = (14.4)/(3)`

• [On Simplification]

=> s = 4.8 cm

Hence,

The required side of the given equilateral triangle is 4.8cm(Ans)
