Answer:
[tex]188\sqrt{2}-8\sqrt{5}[/tex] feet
Step-by-step explanation:
Well the perimeter is the sum of all sides that means
P= lenght + width + lenght + width
P=2(lenght + width)
so
[tex]P=2(2\sqrt{8}+3\sqrt{5}+45\sqrt{8}-7\sqrt{5} )\\\\P=2((2+45)\sqrt{8}+(3-7)\sqrt{5})\\\\P=2(47\sqrt{8}-4\sqrt{5})\\\\P=2(94\sqrt{2}-4\sqrt{5})\\\\P=188\sqrt{2}-8\sqrt{5}[/tex]
