<PRE><B>Question 347192</B>
HI,
*Note; the perimeter of a rectangle is the sum of all sides or P = 2*l + 2*w
.
Let w be the Width
The question states the following to be true
l = w +30
.
2*w + 2*(w +30) = 180
.
Simplify and Solve for w
4*w + 60 = 180
4*w = 120
w = 30in
.
l = w +30
l = 60in  
. 
check your answer
P = 2*l + 2*w
120in + 60in = 180in</PRE>
