Answer:
Width of the rectangle is 8 feet
Length of the rectangle is 13 feet
Step-by-step explanation:
Complete question -
The length of a rectangular garden is three feet less than twice its width. If the perimeter of the garden is 42 feet, what is its length?
Solution
Let the width of the rectangle be X feet
Length of the rectangle would be 2X -3 feet
Perimeter of the rectangle is 2 (length + breadth)
Substituting the given values, we get -
Perimeter = 2 (length + breadth)
[tex]42 = 2 [(2X-3) + X]\\42 = 4X - 6 + 2X\\48 = 6X\\X = 8[/tex]
Width of the rectangle is 8 feet
Length of the rectangle is [tex]2*8 -3 = 16-3 = 13[/tex] feet
