Answer: 624
Step-by-step explanation: We know the width is 104 inches and that the length is twice that. So since 104 times 2 = 208 the length must be 208
to get the perimeter we must add length + length + width + width
so 104 +104+208+208 if we add 104 + 104 =208 so...
208+208+208= perimeter or 208 times 3 = perimeter
so multiply 208 times 3 and you will get 624 which is the perimeter
