Algebra.Com's Answer #99868 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! the x dimension is the difference in the first two points (where y is constant) \n" ); document.write( "__ -0.1-(-7.9)=7.8\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the y dimension is the difference in the 1st and 3rd points (where x is constant) \n" ); document.write( "__ 6.8-(-3.4)=10.2\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the area is just x times y __ 7.8*10.2\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "this works because the rectangle is oriented in line with the axes \n" ); document.write( "__ if it were tilted, you would have to use the distance formula to find the lengths of the sides \n" ); document.write( " |
