Algebra.Com's Answer #381836 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! The area of the picture (without the frame) is 5*7 = 35 square inches\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now add 1 inch to each side (this will mean you're effectively adding 1+1 = 2 inches to each dimension): 5+2 = 7 and 7+2 = 9\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the overall dimensions of the picture and the frame combined are 7\" by 9\"\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The area of this is 7*9 = 63 square inches.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "-------------------------------------------------------\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The area of the frame alone is then the difference between the area of the picture+frame and the picture alone (a drawing may help see this)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the area of the frame is then: \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(Area of picture+frame) - (Area of picture only) = 63 - 35 = 28\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the area of the frame only is 28 square inches.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So if you have a thin strip of material that is 1 inch in width and 28 inches in length, then this would be a starting point for the frame. \n" ); document.write( " |
