Answer:

The length of rectangle =18 m.

Step-by-step explanation:

Suppose of length of rectangle=x

Width of rectangle =[tex]\frac{2}{3}x[/tex]

Area of rectangle =[tex]216 m^2[/tex]

We have to find the length of rectangle .

Area of rectangle =[tex]length\times breadth[/tex]

Substitute the values in the given formula

[tex]216=x\times \frac{2}{3}x[/tex]

[tex]216=\frac{2}{3}x^2[/tex]

[tex]2x^2=216\times 3[/tex] By multiplication property of equality

[tex]x^2=\frac{216\times 3}{2}[/tex] ( by division property of equality )

[tex]x=\sqrt{324}=18[/tex]

Substitute the value then we get

Width of rectangle =[tex]\frac{2}{3}\times 18=12 m[/tex]

Hence, the length of rectangle =18 m.
