P=2L+2W or 2(L+W) so if W=1/4L and P=40 then lets substitute the knowns into our equation 40=2(L+1/4L) solving for L we get 2.5L=40 so L=16 and W=1/4(16) \n" ); document.write( "resulting in W=4\r \n" ); document.write( "\n" ); document.write( "answer: Length = 16 \n" ); document.write( " Width = 4 \n" ); document.write( " |
