Measure of perimeter is found my adding the length of all sides.

karissafrazier:

14+16+60+10+4?

JustBeNice:

60 is the perimeter of the first person's garden.

JustBeNice:

There are four sides, two of which are 14 in length, two are 16.

karissafrazier:

14+14+16+16?

JustBeNice:

That should equal the perimeter of the first garden.

JustBeNice:

What is being asked in this is the perimeter of the second garden. If it is 10 by 4, what are the lengths of each side? Find that, and you can add all the side lengths to get the answer.

karissafrazier:

40 is the length of each side I think

You are going to use the same thinking as this ^

JustBeNice:

The first garden is 14 by 16. This means two sides are 14, two are 16.

sorry if i'm annoying, i just found out a few days ago I have a specific learning disability

JustBeNice:

You are not annoying. It's okay:)

karissafrazier:

14+14+16+16+40+40...?

JustBeNice:

14 + 14 + 16 + 16.

JustBeNice:

Now, for the second garden, that means it will be 10 + 10 + 4 + 4

JustBeNice:

So, what's 10 + 10?

20

JustBeNice:

Okay, what's 4 + 4?

karissafrazier:

8

JustBeNice:

Now, 20 + 8?

karissafrazier:

28

JustBeNice:

There you go:)

JustBeNice:

(Side 1 & 2) 20 + (Side 3 & 4) 8 = 28.

karissafrazier:

it said it was 24- was i like, supposed to do smthn else or smthn?

28, not 24.

JustBeNice:

wait! it wants it in feet! not yards

JustBeNice:

I'm sorry! I didn't notice that. Do you know how to convert yards to feet?

karissafrazier:

multiply if i remember correctly, which i probably don't

JustBeNice:

It's okay:) Each yard is 3 feet.

JustBeNice:

So, what you're going to do is multiply the answer we got, 28, by 3. Then it should be correct:)

JustBeNice:

So, what's 28 x 3?

karissafrazier:

84

karissafrazier:

JustBeNice:

This is a different question, correct?

karissafrazier:

yea

karissafrazier:

prodigy honeslty hates meh

JustBeNice:

Well, this one is easier because no conversions are required.

JustBeNice:

What's 7 + 7?

karissafrazier:

14

JustBeNice:

10 + 10?

karissafrazier:

20

JustBeNice:

20 + 14?

karissafrazier:

34

JustBeNice:

Now, they want you to find the difference between the two perimeters. So, 34 - 28?

karissafrazier:

6

JustBeNice:

Good Job! :)

JustBeNice:

I have to go now. Have a great day!
