This problem looks similar to the other math problem posted here. OwO

Anyway, first represent the unknowns.
Let x = length
since the width is 2/3 of the length,
Let (2/3)x = width

Recall that the area of rectangle is just width multiplied by the length,
A = w * l
Substituting,
864 = (2/3)x * x
864 = (2/3)x^2
864 * 3/2 = x^2
1296 = x^2
Get the square root of both sides,
x = 36 feet (length)

Note that you should only get the positive root since dimensions (length, width, etc.) cannot be negative.

Hope this helps~ `u`
Thank you very much, it helped me a lot. :)
2 plus 2 minus 1 that is 3
it kinda helped me thx alot
