<PRE><B>Question 988671</B>
2L+2W=56;L+W=28
LW=187
L=187/W
187/W+W=28
187+W^2=28W, multiplying by W
W^2-28W+187=0
W=(1/2)(28+/-) sqrt (784-748);sqrt term =6
W=17 or 11
L=11 or 17
By convention, L is longer, so it is 17*11
17,11,17,11 is perimeter
17*11 is area.  
Notice that the roots are interchangeable.
