<PRE><B>Question 1004278</B>
The perimeter of a rectangle is:
2L+2W= P The problem says the Width= L-29 and the Perimeter= 138:
2L+L-29+L-29= 138
4L-58= 138
4L= 196
L= 196/4
L= 49 This is the length, and the width:
W= 49-29= 20
Proof:
2(49)+2(20)= 138
98+40= 138
138= 138 We have the correct answer</PRE>
