Algebra.Com's Answer #258194 by HasanSahin(52)![]() ![]() You can put this solution on YOUR website! The area is (base length*height)/2 as height line intersects the base line perpendicularly. The taller line is height and wide is the base length.\r \n" ); document.write( "\n" ); document.write( "x = base, x+2 = height So that >> (x*(x+2))/2 = 12 >> x^2 +2x -24= 0 >> x = 4 or x = -6 but we can not choose negative value so that x must be 4!\r \n" ); document.write( "\n" ); document.write( "Therefore base = 4 and height = 6 feet.\r \n" ); document.write( "\n" ); document.write( "RF. \n" ); document.write( " |
