Answer:

[tex]\large\boxed{P=60.56\ m}[/tex]

Step-by-step explanation:

The formula of an area of a rectangle:

[tex]A=lw[/tex]

l - length

w - width

We have

[tex]A=229.2\ m^2\\\l=15\ m[/tex]

Substitute:

[tex]15w=229.2[/tex]          divide both sides by 15

[tex]w=15.28\ m[/tex]

The formula of a perimeter of a rectangle:

[tex]P=2(l+w)[/tex]

Substitute:

[tex]P=2(15+15.28)=2(30.28)=60.56\ m[/tex]
