drwls: Is there any way you can explain why you did what you did? I don't understand. You had this:

2 (L + W) = 52 (perimeter)

L*W = 168 (area)

2*168/W + 2W = 52

168/W + W = 26

W^2 - 26W = 168

(W-14)(W-12) = 0

W = 14 or 12 m

If W = 12, L = 14 and vice versa

The pad dimensions are 14 x 12 m.

**bobpursley**, Wednesday, February 3, 2010 at 11:03amThe first two equation are a math statement of what the given is (Perimeter, area).

The rest is algebra, you can do that however you see fit. DrWLS did it by substitution.
