Algebra.Com's Answer #244783 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! a retangle has a area of 72 its length is twice its width what is its perimeter? \n" ); document.write( "---------------- \n" ); document.write( "Area = length * width \n" ); document.write( "---- \n" ); document.write( "Let the width be \"w\" \n" ); document.write( "Then the length is \"2w\" \n" ); document.write( "----- \n" ); document.write( "Solve with substitution: \n" ); document.write( "72 = w*2w \n" ); document.write( "36 = w^2 \n" ); document.write( "w = 6 units (width) \n" ); document.write( "2w = 12 units (length) \n" ); document.write( "--------------------------- \n" ); document.write( "Now, determine the perimeter. \n" ); document.write( "P = 2(L+W) \n" ); document.write( "P = 2(12+6) \n" ); document.write( "P = 2(18) \n" ); document.write( "Perimeter = 36 units \n" ); document.write( "========================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============ \n" ); document.write( " |
