Elemantary school so
area=legnth times width
to get greatest area, make legnth as close to width as possible in measure

to get least area, make legnth as far away from width as possible in measure
perimiter=2 times legnth+2 times width=2 times (legnth+width)
18=2 times (legnth+width)
divide 2
9=legnth+width
find closest and farthest
1+9 is farthest
4+5 is closest

areas=legnth times with
1 times 9=9
4 times 5=20
differnce is subtract
20-9=11

answe is 11
(note I didn't use decimals since the user is supposedly in elemenatry school)

How do functions and slopes work i dont understand anything work?
IrinaK [193]
Slope shows both steepness and direction. With positive slope the line moves upward when going from left to right. With negative slope the line moves down when going from left to right. If two linear functions have the same slope they are parallel.
