Question

What is the perimeter of a triangle Whose all sides are 4.5 long?
​

Answer 1

Answer:

Hence, the perimeter of a triangle is 13.5 unit

Step-by-step explanation:

As per the data provided in the given question

The given data is as follows,

All sides of the triangle (a) are 4.5 unit

We have to find the perimeter of the triangle i.e. (P)

Here, all sides of a triangle are the same therefore it is a equilateral triangle.

So, we will be using the formula of the perimeter of an equilateral triangle

$P=3a$

Now, we will subsituding the values  of side in the above formula

Further we get,

$P=3\times4.5$

At first, we will multiply 5 into 3 we get 15 and after that 4 into 3 get 12

Further we get,

$P=13.5\:unit$

Hence, the perimeter of a triangle is 13.5unit

Note:What is the perimeter of a triangle Whose all sides are 4.5 unit long?

Answer 2

Answer:

Perimeter of a triangle is $13.5 \ unit$ .

Step-by-step explanation:

To find : perimeter of a triangle

Given : all sides of triangle are 4.5 unit .

Solution :

• As per given data we know that , all sides of triangle are 4.5 unit .
• We know that, perimeter of triangle is sum of three side of triangle.
• If $a,b,c$ are the sides of triangle then,
• Perimeter of triangle $=a+b+c$
• Therefore, perimeter of triangle $= 4.5 + 4.5 + 4.5$

                                                              $= 13.5 \ unit$

Note :

Since , unit of measurement of triangle was not given therefore we take it as unit .
