document.write( "Question 1007446: the perimeter of a rectangle is 108 cm. If the length is increased by 5 and the width is doubled. The perimeter becomes 182cm. Find it's dimension. \n" ); document.write( "
Algebra.Com's Answer #623385 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Here perimeter P = 2L + 2W = 108 or L + W = 54 or L = 54 - W \n" ); document.write( "Then in the second case, \n" ); document.write( "2(L + 5) + 2(2W) = 182 \n" ); document.write( "Substitute the first equation into this one and get \n" ); document.write( "2(54 - W + 5) + 4W = 182 \n" ); document.write( "2(59 - W) + 4W = 182 \n" ); document.write( "118 - 2W + 4W = 182 \n" ); document.write( "2W + 118 = 182 \n" ); document.write( "2W = 64 \n" ); document.write( "W = 32 cm \n" ); document.write( "L = 54 - 32 = 22 cm \n" ); document.write( " |
