You are building a walkway of uniform width around a 100ft by 60ft swimming pool.
\n" ); document.write( " After completing the walkway, you want to put a fence along the outer edge of the walkway.
\n" ); document.write( " You have 450ft of fencing to enclose the walkway.
\n" ); document.write( " What is the maximum width of the walkway?
\n" ); document.write( ":
\n" ); document.write( "Actually they are asking for width of the walkway.
\n" ); document.write( ":
\n" ); document.write( "let x = the width of the walkway
\n" ); document.write( "that will add 2x to each dimension of the pool
\n" ); document.write( ":
\n" ); document.write( "the overall dimensions including the walkway will be
\n" ); document.write( "(2x+100) by (2x+60)
\n" ); document.write( ":
\n" ); document.write( "The fencing will equal the perimeter of the area including the walkway
\n" ); document.write( "2L + 2W = 450
\n" ); document.write( "Using the overall dimensions for L and W:
\n" ); document.write( "2(2x+100) + 2(2x+60) = 450
\n" ); document.write( "simplify divide thru by 2
\n" ); document.write( "(2x+100) + (2x+60) = 225
\n" ); document.write( "combine like terms
\n" ); document.write( "4x + 160 = 225
\n" ); document.write( "4x = 225 - 160
\n" ); document.write( "4x = 65
\n" ); document.write( "x = 65/4
\n" ); document.write( "x = 16.25 ft is the width of the walkway if you use 450 ft of fence
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "you can check this by finding the overall dimensions
\n" ); document.write( "(32.5+100) by (32.5+60)
\n" ); document.write( "132.5 by 92.5
\n" ); document.write( ":
\n" ); document.write( "See if this equal the amt of fencing
\n" ); document.write( "2(132.5) + 2(92.5) =
\n" ); document.write( "265 + 185 = 450\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
