<PRE><B>Question 79541</B>
A garden area is 30 ft long and 20 ft wide.  A path of uniform width is set inside the edge.  If the remaining garden is 400ft^2, what is the width of the path.
==========
Probably.
Original Area = 30*20=600 sq ft
New Area = (30-2x)(20-2x)
EQUATION:
If width = x:
600-(30-2x)(20-2x)=400
Solve that quadratic for x.
