Solution :
Given Perimeter (P) of Rectangle = 24 feet
Width of the rectangle (w) = 4 feet
Solving for the Length of the rectangle (L) , therefore P = 2(L) + 2 (w) ,
24 feet = 2 (L) + 2 (4)
24 feet = 2L + 8
24 -8 = 2L
16 feet /2 = L
8 feet = L , Length of the Rectangle.

can you help me **Weegy:** Yes. **User:**
What is the name of the line segment.
would it have a
TU
or -
TU or
->
TU **Weegy:** a TU **User:** ita a line that has a dot at the beginning and a dot at the end. then at the beginnig it is lettered T and at the end its lettered U **Weegy:** In geometry, a line segment is a part of a line that is bounded by two end points, and contains every point on the line between its end points. **User:** but above the TU it either has a line that has arrows at both ends. or a soild line or a line with just one arrow **Weegy:** A line that has arrows at both ends. **User:** The perimeter of the rectangle shown below is 24 feet. What is the length of side x? **Weegy:** The perimeter formula is
P = 2L + 2W
24 = 2(10) + 2(2)
24 = 20 + 24
24 = 24 The Length is 10 Feet
The width is 2 Feet
Method 2
The length is 5 times its width. find the width. [ The perimeter is 24 feet
P = 2L + 2W
24 = 2(5W) + 2W
24 = 10W + 2W
24 = 12W
24/12 = 12W/12
2 = W
The answer is W = 2
The width is 2 feet
The length is 5 times the width.
5 x 2 = 10
The length is 10 feet
~~ - - - - - - s
Finding Perimeter when Length and Width are known
Length = 10
Width = 2
P = 2L + 2W
P = 2(10) + 2(2)
P = 20 + 4
P = 24
