so the two lengths and widths of three fields add up in all 24 meters perimeter... that's small...

remi2019:

ya

remi2019:

it would be 34

snowflake0531:

@AZ i don't get it fsr lol

remi2019:

fsr? means what

snowflake0531:

for some reason *

AZ:

so let's do one field at a time, shall we?

AZ:

Field #1 has a width of 4 the perimeter is 24 for all the fields perimeter = width + width + length + length perimeter = 2*width + 2*length so what is the length if the width is 4 and perimeter is 24

remi2019:

20

remi2019:

or wait 10??

remi2019:

NO IT IS 6 right

snowflake0531:

... nah

AZ:

no no so 24 = 4 + 4 + length + length

remi2019:

so 8

AZ:

there you go! so what would the area be if the width is 4 and the length is 8?

remi2019:

32

AZ:

so that's your number for the first field! now for the second field

AZ:

perimeter is 24 width is 6 what is the length?

remi2019:

6

remi2019:

right

AZ:

good!

AZ:

and what would the area be

remi2019:

36

AZ:

good! now field #3

AZ:

perimeter is 24 and width is 7 what is the length?

remi2019:

5

AZ:

good! and what is the area?

remi2019:

35

remi2019:

tysm

AZ:

good! so now you have all the numbers for part a for part B, just choose the rectangle that gives you the biggest area

remi2019:

2

AZ:

Look at you go! That's correct :)
