Answer:
Your answer would be: y=-4, x=1
To find the largest possible rectangular area, you must find the two highest common factors, which are, in this case is 20 x 10. therefore the answer is 20m x 10m
So all you have to do is take the first numbers of each multiple and multiply them.
1 x 2 x 3 x 4 = 24
Now you just add the 4 zeros to your answer.
240,000
Our answer even checks!
10 x 20 x 30 x 40 = 240,000
Good Luck! :)
I think the answer would be 180
5*2=10 90*2=180
