To find of the area, we do the following:
Declare variables we will use:
Let 'x' be the length of width
Create equation using information we have:
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.
