the length of the rectangular garden is three feet less than twice its width. if the perimeter is 42 feet, what is its length?

Answer:13 feetStep-by-step explanation:Define x :--------------------------------------------Let the width be x.Width = xLength = 2x - 3--------------------------------------------Perimeter Formula :--------------------------------------------Perimeter = 2 (Length + Width) --------------------------------------------FInd Width :--------------------------------------------42 = 2 (x + 2x - 3) 42 = 2(3x - 3)42 = 6x - 648 = 6x 6x = 48x = 8 feet--------------------------------------------Find Length :--------------------------------------------Length = 2x - 3 = 2(8) - 3 = 13 feet--------------------------------------------Answer: The length is 13 feet.
