Algebra.Com's Answer #810299 by Theo(13342)![]() ![]() You can put this solution on YOUR website! the perimeter is 40 centimeters. \n" ); document.write( "the perimeter is equal to 2L + 2W. \n" ); document.write( "L = length \n" ); document.write( "W = width. \n" ); document.write( "when L = W, you can replace L with W or W with L to get: \n" ); document.write( "perimeter = 4L or 4W. \n" ); document.write( "formula for perimeter becomes 4L = 40 or 4W = 40. \n" ); document.write( "this makes L = 10 and W = 10. \n" ); document.write( "the area is L * W = 10^2 = 100 \n" ); document.write( "that should be the maximum area since the maximum area of a rectangle is when the rectangle is a square. \n" ); document.write( "to confirm, you can try any other combination of 2L + 2W = 40 and then find the area. \n" ); document.write( "the possible combinations are shown below: \n" ); document.write( "you can see that the maximum area is when L = W.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " ![]() \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
