Algebra.Com's Answer #425679 by sachi(548)![]() ![]() You can put this solution on YOUR website! The length of a side of the larger square is 3 cm more than the length of a side of the smaller square. \n" ); document.write( "let the side of the smaller square is a cm then larger square has sides a+3 cm\r \n" ); document.write( "\n" ); document.write( "The sum of the area of two squares is 89 square centimeters. \n" ); document.write( "so a^2+(a+3)^2=89 \n" ); document.write( "or a^2+a^2+9+6a=89 \n" ); document.write( "or 2a^2+6a-80=0 \n" ); document.write( "or a^2+3a-40=0 \n" ); document.write( "or a^2+8a-5a-40=0 \n" ); document.write( "or a(a+8)-5(a+8)=0 \n" ); document.write( "or (a+8)(a-5)=0 \n" ); document.write( "or a+8=0=> a=-8 rejected for -ve value \n" ); document.write( "then (a-5=0 =>a=5 the side of the smaller square \n" ); document.write( "& the sides of the larger square is 3+5=8 cms \n" ); document.write( "ans \n" ); document.write( " \n" ); document.write( " |
