: I have tried to do this problem but no luck. It seems simple but I can't find the answer. The question is: A rectangle has a length that is twice as long s the width. If the area is 24m squared what is the length and width of the rectangle. I know all the multiples of 24, but nothing seems to work.
Thanks,

You can put this solution on YOUR website! A rectangle has a length that is twice as long as the width. If the area is 24m squared what is the length and width of the rectangle. I know all the multiples of 24, but nothing seems to work.
:
Let x = width of the rectangle
Then
2x = length of the rectangle
:
Length * width = 24
2x * x = 24
:
2x^2 = 24
:
x^2 = 24/2
:
x^2 = 12
:
x = sqrt(12)
:
x = sqrt(4*3)
:
x = 2*sqrt(3) is the width of rectangle
then
2(2*sqrt(3))
:
4*sqrt(3) = length of the rectangle
:
:
Check solution: 4*sqrt(3) * 2*sqrt(3) = 8 * 3 = 24
