Question

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

A.h=2A-b
B.h=2Ab
C.h=2A/b
D.h=A/2b

Answer 1

The answer is C.

Multiply each side by 2, and divide both sides by B to isolate H.

The 1/2 and B would cancel out the same side as H.

Answer 2

Solve the formula for h, so you need to isolate/get h by itself in the equation:

A = 1/2bh Multiply the inverse of 1/2, which is 2/1 or 2 on both sides to get rid of the 1/2

`((2)/(1))A=((2)/(1))(1)/(2)bh`

2A = bh Now divide by b on both sides

`(2A)/(b) =(bh)/(b)`

`(2A)/(b) =h` Your answer is C
