  1. the actual value does not matter

    replacing h by 4h, we have the new area is

    b(4h)/2 = 4(bh/2)
    so the area is increased by a factor of 4

  3. You are wrong Steve. Very wrong Steve. So wrong I am laughing right now Stve. The actual answer is C because you subtract 20 from 10 which is 10 and then subtract 2 which is 8.
