Question
A base of a triangle has length b, the altitude corresponding to the base has length h, and b=2h. Which of the following expresses the area of the triangle, in terms of h?
(A) 1/2 h^2
(B) 3/4 h^2
(C) h^2
(D) 3/2 h^2
(E) 2 h^2

• Formula: Area = 1/2 x base x height
  area = a
  height = h
  base = b = 2h
  
  a = 1/2 x 2h x h
  a = 1/2 x 2h/1 x h/1
  a = 2h^ 2/2
  a = h^ 2
