Algebra.Com's Answer #369532 by chana(69)![]() ![]() You can put this solution on YOUR website! The length of a rectangle is 5 meters longer than the width. The area is 300 square meters. How long is the rectangle? \n" ); document.write( "sol: \n" ); document.write( "let the unknown parameter width be x \n" ); document.write( "and length = 5 + x , as given \n" ); document.write( "area = 500 sq units \n" ); document.write( "l * width = area \n" ); document.write( "so subtitute what you know in the above equation \n" ); document.write( "(5 + x)*(x) = 300------------- 1 \n" ); document.write( "the above equation is the required one to find the length. \n" ); document.write( "solve for x which gives length = 15 meter\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
