Question 727829: the width of the door is 3.4 feet and the perimeter of the door is 22.8 feet. What is the length of the door? Answer by luvmath123(1) (Show Source):
You can put this solution on YOUR website! The perimeter of the door is all of the sides added together. Because a door is a rectangle, there are four sides. Two are the width and two are the length. We know the width is 3.4 feet and because there are two that is a total of 6.8 feet. We can use the following equation to solve for the length.
Length+Length+Width+Width=Perimeter
Length+Length+3.4+3.4=22.8
Length+Length=16
Length=8
The length is 8 feet
