Each Morning Jarilyn runs a total distance of 42 city blocks and always chooses a rectangular running path. This morning her rectangular path was twice as long as it was wide. How many blocks long and how many blocks wide was this mornings rectangular path?
\n" ); document.write( "..
\n" ); document.write( "Let width of area covering 42 blocks be x
\n" ); document.write( "length = 2*x = 2x.
\n" ); document.write( "..
\n" ); document.write( "He runs round the 42 blocks in rectangular path.
\n" ); document.write( "Perimeter = 42 blocks
\n" ); document.write( "Perimeter P = 2*(L+W)
\n" ); document.write( "2*(x+2x)=42
\n" ); document.write( "2*3x=42
\n" ); document.write( "6x=42
\n" ); document.write( "divide by 6
