Algebra.Com's Answer #793998 by Boreal(15235) You can put this solution on YOUR website! x is length of side of a square and x*x or x^2 is the area. \n" ); document.write( "width of rectangle ix (x-6) and length is (2x+9), so the area is (x-6)(2x+9)\r \n" ); document.write( "\n" ); document.write( "Can check this \n" ); document.write( "area of rectangle is 2x^2-3x-54=x^2 area of square \n" ); document.write( "x^2-3x-54=0 \n" ); document.write( "(x-9)(x+6)=9 \n" ); document.write( "x=9 in \n" ); document.write( "so area of square is 81 in^2 \n" ); document.write( "sides of rectangle are 3 in and 27 in and its area is 81 in^2. \n" ); document.write( " |
