### Project Main Details

**Mathematics Voiceover**

**ZDLTK53306389282X**Hi,

We, an Australian educational website, are seeking competent and eligible candidate who would be the voiceover for our mathematics animated topic wise videos from Grade 3 to Grade 12. We’ll provide the story board (topic wise) and every individual video’s length would be approximately 7 to 10 minutes. If one feels the necessity then he/she must edit the story board and then deliver. In total, there would be approximately 800 videos of length 7 to 10 minutes.

The prerequisites for applying are as follows:

1. Excellent accent & communication skill with kids

2. Adequate mathematical knowledge

3. Dedication

More details will be given if contacted.

Interested ones are advised to contact as soon as possible.

Regards,

The prerequisites for applying are as follows:

1. Excellent accent & communication skill with kids

2. Adequate mathematical knowledge

3. Dedication Intro

In this lesson you are going to learn the perimeter of different shapes.

1

Perimeter of a shape is the distance around it.

2

For this triangle perimeter is the summation of its sides.

3

So Perimeter, P = a + b +c

4

There are three ways in which we can find the perimeter of a given shape.

They are:

Through Measurement

Through Calculation

Through The Formula

5

Measure the length of each side using a ruler. Then add the measurements to get the perimeter.

6

A length of the shape is missing; find this length and then add all the lengths to find the perimeter of the shape.

7

In this example, one side of the triangle is missing which is 15m. So perimeter is (15+15+10) = 40 m

8

Finding the perimeter of a shape through the formula:

All regular shapes have their individual formulas for calculating their perimeter.

9

For any square of side length s unit:

Perimeter, P = s+s+s+s

P = 4s

10

For any rectangle of length l units and breadth b units:

Perimeter, P = l+b+l+b

P = 2(l+b)

11

Now, let us have a look at the following composite shape. How can you find the perimeter of this shape?

12

As you can see, two of the lengths are missing. Find the missing lengths and add them with the given lengths to find the perimeter of the shape.

13

Hence, the perimeter (P) of this composite shape would be:

P = (26 + 12 + 14 + 3 + 12 + 15) m

= 82 m

14

Now, what is the perimeter of the following right-angled triangle?

15

Since one side is missing, Use Pythagoras’ theorem to find the length of the hypotenuse.

h2 = 362 + 482

h2 = 3600

h = 60

So, Perimeter P=36+48+60 m

P = 144 m

16

Ok, now here are some questions for you to answer.

17

Can anyone tell me what would be the perimeter of this triangle?

18

Excellent! Well done.
