By definition, the area of a rectangle is given by:
[tex] A = w * l
[/tex]
Where,
w: width of the rectangle
l: length of the rectangle
Substituting values in the given equation we have:
[tex] 864 = (\frac{2}{3} l) * (l)
[/tex]
From here, we clear the value of l.
We have then:
[tex] l ^ 2 = (\frac{3}{2}) * (864)
l ^ 2 = 1296
[/tex]
[tex] l = \sqrt{1296}
l = 36
[/tex]
Answer:
