Algebra.Com's Answer #97624 by jojo14344(1513)![]() ![]() ![]() You can put this solution on YOUR website! Given: \n" ); document.write( "Width (W) = x (unknown) \n" ); document.write( "Length (L) = 3 times the width = 3W = 3x \n" ); document.write( "Perimeter (P) = 22 \n" ); document.write( "Formula: \n" ); document.write( "P = 2(L+W) \n" ); document.write( "Substitution, \n" ); document.write( "22 = 2 ( 3W + W ) \n" ); document.write( "22 = 2 ( 3x + x) \n" ); document.write( "22/2 = 4x \n" ); document.write( "x= 2.75 ( width ) \n" ); document.write( "Therefor the length (L) = 3 W = 3 (2.75) \n" ); document.write( " L = 8.25 \n" ); document.write( "To check: \n" ); document.write( "P = 2 (L + W) \n" ); document.write( "22= 2 (8.25 + 2.75) \n" ); document.write( "22= 2 (11) \n" ); document.write( "22= 22\r \n" ); document.write( "\n" ); document.write( "Therefore, having Width = 2.75 is correct because it will arrived to a Perimeter of 22 as shown in th equation. Good Job! \n" ); document.write( " |
