Building a walkway of uniform width around 95x65 foot swimming pool.
\n" ); document.write( " After walkway is complete, you want to build a fence around outer edge of walkway.
\n" ); document.write( " You have 450 ft of fencing to enclose the walkway. What is the maximum width of the walkway?
\n" ); document.write( ":
\n" ); document.write( "Let x = the walkway width
\n" ); document.write( "Then the overall dimensions, including the walkway:
\n" ); document.write( "(2x+95) by (2x+65)
\n" ); document.write( ":
\n" ); document.write( "The perimeter: 2L + 2W = 450:
\n" ); document.write( "therefore:
\n" ); document.write( "2(2x+95) + 2(2x+65) = 480
\n" ); document.write( ":
\n" ); document.write( "Simplify, divide by 2
\n" ); document.write( "(2x+95) + (2x+65) = 240
\n" ); document.write( ":
\n" ); document.write( "Remove brackets, group like terms
\n" ); document.write( "2x + 2x + 95 + 65 = 240
\n" ); document.write( "4x + 160 = 240
\n" ); document.write( "4x = 240 - 160
\n" ); document.write( "4x = 80
\n" ); document.write( "x = \"80%2F4\"
\n" ); document.write( "x = 20' is the width of the walkway
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check by finding the perimeter
\n" ); document.write( "2(95 + 2(20)) + 2(65 + 2(20))
\n" ); document.write( "2(95 + 40) + 2(65 + 40)
\n" ); document.write( "2(135) + 2(105)
\n" ); document.write( "270 + 210 = 480
\n" ); document.write( "
