Question 519453
The length of a rectangle is 7 meters longer than its width. What is the width of this rectangle if its perimeter is equal to 86 meters? 
----
Let width be "W"
Then length  is "W+7"
----
Perimeter = 2(length + width)
86 = 2(W+7 + W)
43 = 2W+7
2W = 36
Width = 18 meters 
----
Solve for length:
length = W +7 = 25 meters
