Answer:
The answer is the first one A=200ft^2
Explanation:
Width's length is equal to 2x because a rectangle has two width 
Length's length is equal to 4x because we know that the length of the rectangle is twice its width. So that is 2x. Since there is two length of a rectangle, its 2x * 2 = 4x. 
 
The equation is 4x + 2x = 60 feet 
6x = 60 
 
Find the x to find perimeter and area: 
6x = 60 Divide both side by 6 
x = 10 
 
Width = 10 feet 
Perimeter = 2x = 2(10) = 20 feet 
 
Area = 10 * 20 = 200 feet² 
 
Therefore, the answer is 200 feet².
