Question

Please please help!!!!!

Answer 1

Answer:

$188\sqrt{2}-8\sqrt{5}$ 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

$P=2(2\sqrt{8}+3\sqrt{5}+45\sqrt{8}-7\sqrt{5} )\\\\P=2((2+45)\sqrt{8}+(3-7)\sqrt{5})\\\\P=2(47\sqrt{8}-4\sqrt{5})\\\\P=2(94\sqrt{2}-4\sqrt{5})\\\\P=188\sqrt{2}-8\sqrt{5}$
