<human>:  A rectangular flowerbed in the city park is 4 meters wide. Its length is 1 meter less than twice its width. The government wants to fence the flowerbed. How many meters of fence are needed?
<bot>: How many meters is the flowerbed? ** Twice the width is 4 x 2 = <<4*2=8>>8 meters.
How many meters is the length of the flowerbed? ** The length of the rectangular flowerbed is 8 - 1= <<8-1=7>>7 meters.
How many meters of fence are needed? ** Since the rectangular flower bed has 2 equal lengths, then it needs 7 x 2 = <<7*2=14>>14 meters of fence.
How many meters of fence are needed? ** The rectangular bed has also 2 equal widths, so it needs 4 x 2 = <<8=8>>8 meters of fence.
How many meters of fence are needed? ** Therefore, the rectangular flower bed needs a total of 14 + 8 = <<14+8=22>>22 meters of fence.
