The length of a rectangular playing field is 5 ft. less than twice its width. If the perimeter of the playing field is 230 ft., find the length and width of the field.
\n" ); document.write( ":
\n" ); document.write( "Write this sentence as an equation:
\n" ); document.write( "\"The length is 5 ft less than twice its width.\"
\n" ); document.write( "L = 2*W - 5
\n" ); document.write( ":
\n" ); document.write( "The perimeter equation: 2L + 2W = 230
\n" ); document.write( ":
\n" ); document.write( "From the 1st statement, we know that L = (2W-5)
\n" ); document.write( "Substitute (2W-5) for L in the perimeter equation and solve for W:
\n" ); document.write( ":
\n" ); document.write( "2(2W-5) + 2W = 230
\n" ); document.write( ":
\n" ); document.write( "4W - 10 + 2W = 230
\n" ); document.write( ":
\n" ); document.write( "6W = 230 + 10
\n" ); document.write( ":
\n" ); document.write( "W = 240/6
\n" ); document.write( ":
\n" ); document.write( "W = 40 ft
\n" ); document.write( ":
\n" ); document.write( "I'll let you find the Length (L), check the values in the Perimeter equation \r
