Algebra.Com's Answer #501904 by JulietG(1812) You can put this solution on YOUR website! A = (L * W) / 2(for a triangle instead of a rectangle) \n" ); document.write( "We know that L = 3 \n" ); document.write( "We can find W by using a^2 + b^2 = c^2 \n" ); document.write( "3^2 + W^2 = 5^2 \n" ); document.write( "9 + W^2 = 25 \n" ); document.write( "Subtract 9 from each side \n" ); document.write( "W^2 = 16 \n" ); document.write( "Square root \n" ); document.write( "W = 4\r \n" ); document.write( "\n" ); document.write( "Now we just multiply L * W \n" ); document.write( "3 * 4 = 12 \n" ); document.write( "Half of that (for a triangle) is \n" ); document.write( "6 <<-- \n" ); document.write( " |
