nicer than scary subway rats remember area is the measurement of the inside of

00:39

a space while the perimeter is the distance around the outside of a space

00:43

so any space is going to have both an area and a perimeter and since the world [image of a large sports stadium]

00:47

is full of all sorts of different spaces area and perimeter come up all over the

00:51

place if you're a bit dizzy from being surrounded by so many instances of [woman looking very confused]

00:55

mathematical concepts feel free to sit down in an area Sorry Sorry feeling

01:00

better awesome let's take a look at a couple of real-world examples of area

01:04

and perimeter say we're trying to make a garden in our backyard and we trace out [a man standing in a back garden]

01:08

a plot where our garden will go if we want to figure out how much soil will

01:12

need for the garden we'll need to figure out the total amount of space in the

01:15

garden which means finding its area on the other hand if we want to surround

01:18

[a white fence surrounding the garden area] the garden with a fence then we'll need to figure out the total distance around

01:22

the garden in other words we've got to find it perimeter if we get these two

01:27

tasks backwards we're going to end up with a garden full of fence post trying

01:30

to buy big piles of dirt similarly area and perimeter can come up if we're

01:34

[a blank yellow painted wall] painting a room if one person decides to paint an entire wall they'll be covering

01:38

the walls area on the other hand if another person decides that they want to

01:41

paint the border of the room they'll be paging the rooms perimeter whether [yellow wall painted pink around the perimeter]

01:44

they're painting areas or perimeters they definitely need to make sure that they

01:48

coordinate what they're doing because even mathematical concepts can't protect

01:52

you from pink getting all over the place [lots of yellow and pink paint splattered on furniture]
