Answer:
P=380 ft.
Explanation:
Area=length x width
Perimeter= 2*length + 2*width
Width= 4*length + 8
A=5472 ft²
5472= l * (4l +8) (plug in values)
5472 = 4l² +8l (simplify)
4l² + 8l - 5472 = 0 (subtract 5472)
4(l² + 2l -1368) = 0 (factor out a 4)
4(l +38)(l-36)=0 (factor)
l=36 ft. (-38 is extraneous because it is negative)
5472=38*w
w=152 ft.
P=2(38) + 2(152)
P= 380 ft.

- <em>A solid is a sample of matter that retains its shape and density when not confined, A liquid is a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity.</em>
I hope this gives you some sort of assistance.
Reread the textbook just to make it better <em>(if you can quickly look through it)</em>
Anyways goodluck!
