c. the area will increase by a factor of 8
d. the area will not change
p.s i cant post the image but the height is 10m and the base is 20m

Answer 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

Answer 2

Thx Steve

Answer 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.
