Ответ:
Width = x
Length = 2x
Given that area is 50 ft², we plug in the value to solve for x:
x (2x) = 50
2x² = 50
x² = 25
x = √25
x = 5
Now that we know x, we find the length and the width:
Width = x = 5
Length = 2x = 2 x 5 = 10
With the length and the width, we find the perimeter of the fence:
Perimeter = 2( 5 + 10) = 30 feet
Finally, we calculate the cost of the fence:
I ft = $3
30 ft = $3 x 30 = $90
The total price of the fencing is $90.
