Therefore 140 = 1/2 bh.  If we double the base and double the height then we have 2b for the base and 2h for the height.   Then the area of the new triangle would be 1/2 * 2b*2h  or 2bh.  If we look at the original triangle with area 140 = 1/2bh then bh = 280 (by multiplying both sides by 2).  Now for the new triangle<BR>\n" );
