document.write( "Question 941930: The perimeter of a rectangle is 22 inches. The length of the rectangle is 10 inches more than the width of the rectangle. Find the length and width. \r
\n" ); document.write( "\n" ); document.write( "I know that the perimeter of a rectangle is P=2l+2w, so 22=2l+2w. I think you have to add the 10 multiplied by the 2l, but I'm not sure.

width=W length=L=W+10
\n" ); document.write( "P=2L+2W=2(L+W)
\n" ); document.write( "22=2(L+W) divide both sides by 2
\n" ); document.write( "11=L+W Substitute for length
\n" ); document.write( "11=W+10+W
\n" ); document.write( "11=2W+10 Subtract 10 from each side
\n" ); document.write( "11-10=2W+10-10
\n" ); document.write( "1=2W divide both sides by 2
\n" ); document.write( "1/2=W
\n" ); document.write( "L=W+10=10 1/2
\n" ); document.write( "CHECK:
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "22=2(10 1/2 + 1/2)
\n" ); document.write( "22=2(11)
\n" ); document.write( "22=22
\n" ); document.write( "
\n" );
