Algebra.Com's Answer #87040 by mayank(15)![]() ![]() ![]() You can put this solution on YOUR website! here let width be W and length be L \n" ); document.write( "From given details width is 5 inches shorter than length, thus W=L-5\r \n" ); document.write( "\n" ); document.write( "now perimeter of rectangle is 50. \n" ); document.write( "thus 50=2(L+W)\r \n" ); document.write( "\n" ); document.write( "thus P=2(L+L-5) \n" ); document.write( "thus P=2(2L-5) \n" ); document.write( "thus P=4L-10\r \n" ); document.write( "\n" ); document.write( "b)now as p=50, 50=4L-10; \n" ); document.write( "thus 60=4L \n" ); document.write( "thus L=60/4 \n" ); document.write( "thus L=15 \n" ); document.write( " |
