Algebra.Com's Answer #497697 by Seutip(231)![]() ![]() You can put this solution on YOUR website! The length of a red rectangle is 15 cm more than its width w. A blue rectangle, which is 5cm wider and 2 cm shorter than the red one, has a perimeter of 72 cm. make a sketch of the rectangles expressing all dimensions in terms of w. Than find the dimensions of each rectangle. \r \n" ); document.write( "\n" ); document.write( "let \n" ); document.write( "x - be the width of the red rectangle \n" ); document.write( "x+15 - be the length of the red rectangle\r \n" ); document.write( "\n" ); document.write( "x+5 - be the width of the blue triangle \n" ); document.write( "x+13 - be the ength of the blue triangle\r \n" ); document.write( "\n" ); document.write( "Perimeter of the blue triangle is 72 \n" ); document.write( "2(x+5) + 2(x+13) = 72 \n" ); document.write( "2x+10+2x+26=72 \n" ); document.write( "4x=36 \n" ); document.write( "x=9\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x - be the width of the red rectangle = 9 \n" ); document.write( "x+15 - be the length of the red rectangle = 24\r \n" ); document.write( "\n" ); document.write( "x+5 - be the width of the blue triangle = 14 \n" ); document.write( "x+13 - be the ength of the blue triangle = 22\r \n" ); document.write( "\n" ); document.write( "The perimeter of the red rectangle is 66\r \n" ); document.write( "\n" ); document.write( "HOPE THAT HELPS! :) \n" ); document.write( " |
