A triangle has base b and height h. The base is doubled. Complete the description of how the height must change so that the area remains the same. Complete the explanation of the reasoning. The area of the original triangle is 1 2 b1h1. The area of the new triangle is 1 2 (2b1)h2 = This must equal the original area, 1 2 b1h1. Therefore, the height must be
