If the width of the rectangle is 13.93 feet. Then the length of the fence that is around the rectangular yard is 83.57 ft.
What is a rectangle?
It has four sides and is a polygon. The internal angle adds up to 360 degrees. The opposing sides of a rectangle are parallel and equal, and each angle is 90 degrees. Its diagonals are equally equal, intersecting at the middle.
You want to build a fence around a rectangular yard. The width is 1/2 the length and the area of the rectangle is 388 square feet.
Let width be x and y be the length of the rectangle.
x = (1/2)y
y = 2x
Then the area of the rectangle is given as
Area = Length × Width
388 = 2x × x
x = 13.93 feet
Then the length of the fence will be
Fence length = 2(x + y)
Fence length = 2(x + 2x)
Fence length = 2(3x)
Fence length = 6x
Fence length = 6 × 13.93
Fence length = 83.57 ft
