Answer: width is 10 inches.
Length is 20 inches
Explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The length of a rectangular yard is twice as long as it is wide. This means that
L = 2W
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The perimeter is 60 inches. This means that
60 = 2(L + W)
L + W = 30 - - - - - - - 1
Substituting L = 2W into equation 1, it becomes
2W + W = 30
3W = 30
W = 30/3 = 10 inches
L = 2W = 2 × 10
L = 20 inches
