a retired public school teacher wanted to build a house with a floor area of 200 sq.m. if the length is to be twice ist width, what should the dimensions be?
Ans:
Let the width be x
Then the length is 2*x
Area = length * width = 

So  or  taking only the positive square root.

Therefore, width is 10m and length is 20m. Area = 20*10 = 200 sq.m. Check!

Hope this helps :)
