so we are given P-perimeter as 52 feet we know that P=2(L+W) the length or L is 4 more fee than the width L=W+4 so substitution our given and the L value in the 2nd equation into our perimeter formula we get 52=2((W+4)+W) lets distribute the right side 52=4W+8 so subtract 8 both sides and 4W=44 divide each side by 4 and W=11 L=W(11)+4 so L=15\r
\n" ); document.write( "\n" ); document.write( "a. width is 11 feet
\n" ); document.write( " length is 15 feet\r
\n" ); document.write( "\n" ); document.write( "b A=15 times 11=165 sq ft but we must divide this by 9 to get square yards
\n" ); document.write( " so 165/9=18.33 sq yards
\n" ); document.write( " so 18.33 sq yd multiplied by cost per yard of $18.95 equals $347.35 as being the cost of the carpet for this given room
\n" ); document.write( "
\n" );
