The question is asking for what length of fencing you need to enclose the garden, what you are doing is finding the area which would be the same as saying that you wanted to fill the whole inner spacing of the garden rather what we really want which is around the outside of the garden

When you find the perimeter of an object, let's us an example of a square and lets say that we know the lengths of all the sides of the square

basically what we do to find the perimeter is to find the "fencing" or the sum of the lengths of the outside of the box

16?

My example was to help you understand trying to find the perimeter of something
juanjohnguy

So now that you know that all you need to do is add up the lengths of all the sides, try doing it for the problem that was given to you

You need to find the lengths of x and then you need to find the length of y

Well you can notice that the object is not a full rectangle, it almost appears as if a piece was taken out of it

Let me explain my picture here so i don't confuse
juanjohnguy
Best Response
You've already chosen the best response.

Basically since i added a piece to make it into a rectangle, we notice that for the right side of the completed rectangle.....when we add the missing piece, that side must be the same length as the other side and we see that the other side (the left side) has a length of 4......the same thing applies for the bottom part.....we notice that now that i added the missing piece to form a perfect rectangle, the bottom needs to be the same length as the top so the bottom (with the missing piece) need to be 6 just like the length of the top

So then with this final picture we can see that when we take the missing piece back out, we have the picture that is given as your problem but we still notice that the bottom needs to equal to a length of 6 and the right side needs to equal to a length of 4
juanjohnguy
Best Response

1
so to make things more simple, to find the length of x we need to think " 2 + what = 6"
and to find the length of y we need to think "1 + what = 4

8

and 5
juanjohnguy

You've already chosen the best response.

So you think that x is 8 and y is 5?
Faman39
Best Response

yes u told to add, thats y
juanjohnguy
Best Response

I meant to say one plus what number equals 4 to find x
juanjohnguy
Best Response
You've already chosen the best response.

oops
sorry i meant y
juanjohnguy
Best Response
You've already chosen the best response.
1
so one plus "a number" equals 4 to find y
juanjohnguy
Best Response
You've already chosen the best response.

and 2 plus "a number" equals 6 to find x

Well so what you are saying when you say that x = 5 and y= 8 is that
2 + 5 = 6
and
1 + 8 = 4
Faman39
Best Response
You've already chosen the best response.

8 + 1 would be the 4?
Faman39
Best Response

it suppose to be 9?

let me restate what i was trying to ask
Faman39
Best Response
You've already chosen the best response.
0
oh ok
juanjohnguy
Best Response
You've already chosen the best response.
1
1 + y = 4
2 + x = 6
juanjohnguy
Best Response
You've already chosen the best response.
1
and I'm asking you to solve for y in the first equation
juanjohnguy
Best Response
You've already chosen the best response.
1
and then solve for x in the second equation
Faman39
Best Response
You've already chosen the best response.

y is 5 and x is 8, right?
juanjohnguy
Best Response
You've already chosen the best response.

Not quite, let me show you how to do the first one and then try to do the second one by yourself again

so the -1 under the 1 and the 4 shows that i subtracted 1 from both sides so that i could get rid of the one that was connected to the y
juanjohnguy
Best Response
You've already chosen the best response.
1
also the way I got rid of the 1 from the right is that we know that the one on the left side is a positive one and to get rid of it we want to make that one turn to a zero......so we subtract from a positive one so that 1- 1 = 0 which is how we can get the y by itself
Faman39
Best Response

second is 4
juanjohnguy
Best Response

Yes you are right for the second one
Faman39

x = 4
Faman39
Best Response

same way i have to subtract
Faman39
Best Response

got this
juanjohnguy
Best Response
You've already chosen the best response.
1
so then now we know what y is and x is then we put them in for the lengths of the object
juanjohnguy
Best Response
You've already chosen the best response.
1
and add the lengths of all the sides
