A rectangular pad of concrete is outlined by a 52m stripe of paint. Find the dimensions of this pad if the surface area is 168m^2.

Math

2 (L + W) = 52 (perimeter)
L*W = 168 (area)
2*168/W + 2W = 52
168/W + W = 26
W^2  26W = 168
(W14)(W12) = 0
W = 14 or 12 m
If W = 12, L = 14 and vice versa
The pad dimensions are 14 x 12 m.
