Arectangular field is 400 meters long and 300 meters wide area in square kilometers

120 kilometers ()

Step-by-step explanation:

first find the area in meters:

400*300 = 120000

now convert from meters to kilometers

1000 meters = 1 kilometer, therefore:

120000/1000

Simplify

120 kilometers ()

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
