The length of rectangle =18 m.

Step-by-step explanation:

Suppose of length of rectangle=x

Width of rectangle = $\frac{2}{3}x$

Area of rectangle = 216 m^2

We have to find the length of rectangle .

Area of rectangle = $length\times breadth$

Substitute the values in the given formula

$216=x\times \frac{2}{3}x$

$216=\frac{2}{3}x^2$

$2x^2=216\times 3$ By multiplication property of equality

$x^2=\frac{216\times 3}{2}$ ( by division property of equality )

$x=\sqrt{324}=18$

Substitute the value then we get

Width of rectangle = $\frac{2}{3}\times 18=12 m$

Hence, the length of rectangle =18 m.
