You can put this solution on YOUR website!
So Perimeter of a rectangle is equal to 2 times the length plus two times the width.
\r
\n" ); document.write( "\n" ); document.write( "Lets let x = the width of the rectangle. Then we know the length is x+5 since the length of the rectangle is 5m longer than the width.
\r
\n" ); document.write( "\n" ); document.write( "so we can plug x and x+5 into the formula for perimeter and solve for x. The euqation is:
\r
\n" ); document.write( "\n" ); document.write( "122 = 2(x+5)+2x
\r
\n" ); document.write( "\n" ); document.write( "I will leave you to solve this but you should get x = 28m. We need to plug this into x+5 to find the length which should give you 33m. \n" ); document.write( "

\n" );
