The length of a table is 5 meters greater than the width. The area of the table is 104m squared. What is the leng
\n" ); document.write( "th and width?
\n" ); document.write( "-----------------
\n" ); document.write( "let width be W
\n" ); document.write( "then length is W+5
\n" ); document.write( "----
\n" ); document.write( "Area = length * width
\n" ); document.write( "104 = w(w+5)
\n" ); document.write( "104 = w^2+5w
\n" ); document.write( "w^2+5w-104 = 0
\n" ); document.write( "Use Quadratic formula:
\n" ); document.write( "w = [-5+-sqrt(25-4*-104)]/2
\n" ); document.write( "Positive solution:
\n" ); document.write( "w = [-5+sqrt(441)]/2
\n" ); document.write( "etc.
