Question

The formula of the area of a triangle is A=1/2bh. Solve the formula for h.

Answer 1

A= 1/2bh
A= bh/2
2A = bh
2A/b = h

Answer 2

A = 1/2bh                Original Problem.
1/2bh = A                Flip Flopped the Equation around.
bh = 2A                   Multiplied both sides by 2.
h = 2A/b                 Divided both sides by b (the base).

Answer: h = 2A/b
