Algebra.Com's Answer #371990 by ankor@dixie-net.com(22740) You can put this solution on YOUR website! \"The length of a rectangle exceeds it's width by 3 meters. \n" ); document.write( " The perimeter is 58 meters. Find the dimensions.\" \n" ); document.write( ": \n" ); document.write( "The perimeter: 2L + 2W = 58 \n" ); document.write( "We can simplify this, divide by 2, and you have \n" ); document.write( "L + W = 29 \n" ); document.write( ": \n" ); document.write( "We know: L = (W+3) \n" ); document.write( ": \n" ); document.write( "(W+3) + W = 29 \n" ); document.write( "2W = 29 - 3 \n" ); document.write( "2W = 26 \n" ); document.write( "W = 13 is the width \n" ); document.write( "then \n" ); document.write( "13 + 3 = 16 is the Length \n" ); document.write( "; \n" ); document.write( "Now you check this in the perimeter equation \n" ); document.write( " |
