Answer:
[tex] P = 3L + 4W= 3*30 ft + 4*30 ft = 210 ft[/tex]
So then is required at least 210 ft in order to satisfy the conditions.
Step-by-step explanation:
For this case we can assume that the rectangular enclosure is on the figure attached.
The perimeter on this case is given by:
[tex]P = 3L + 4W[/tex]
We know that the total area is [tex] 1800ft^2[/tex] and the total area is given this formula:
[tex] A= 2L W[/tex]
Because we have two identical rectangular pieces.
And we can find the value for W like this:
[tex] W = \frac{A}{2L} =\frac{1800 ft^2}{2*30 ft}= 30ft[/tex]
And then we can find the perimeter like this:
[tex] P = 3L + 4W= 3*30 ft + 4*30 ft = 210 ft[/tex]
So then is required at least 210 ft in order to satisfy the conditions.
