# How do you find the perimeter of a triangle if the altitude of an equilateral triangle is 32cm?

##### 2 Answers

#### Explanation:

Ia a is a side length, altitude =

So, the perimeter = 3a =

#### Explanation:

This is solvable by comparing to a standardised triangle and then using ratios.

The perimeter of the standardised equilateral triangle is

The 'altitude' of the standardised triangle is

The given 'altitude' in the question is 32 cm

Let the length of 1 side be

Let the perimeter be

Then by ratio of

Then

Multiply by 1 but in the form of

As an approximate figure
