Algebra.Com's Answer #250584 by mananth(16946)![]() ![]() You can put this solution on YOUR website! Area of triangle = 1/2*base * height. \n" ); document.write( "Area = 165 sq.ft \n" ); document.write( "let base be x \n" ); document.write( "height = x+4\r \n" ); document.write( "\n" ); document.write( ".. \n" ); document.write( "A= 1/2 * x*(x+4) \n" ); document.write( "1/2 *(x^2+4x)=165 \n" ); document.write( "x^2+4x = 330\r \n" ); document.write( "\n" ); document.write( "x^2+4x-330=0 \n" ); document.write( "solve for x using quadratic formula \n" ); document.write( "b^2-4ac= 16+1320=346 \n" ); document.write( "(-4+sqrt(1336)) /2 \n" ); document.write( "=16.27 base \n" ); document.write( "height = 20.27 \n" ); document.write( " |
