Answer:

4x^2 +22x -12

Step-by-step explanation:

The area of a triangle is

A =1/2 bh  where b is the base and h is the height

A =1/2 ( 4x-2) ( 2x+12)

  Distribute

  = (2x-1) ( 2x+12)

FOIL

  first  2x*2x = 4x^2

 outer   2x * 12 = 24x

 inner  -1 *2x = -2x

last   -1 * 12 = -12

Add them together

4x^2 +24x -2x -12

Combine like terms

4x^2 +22x -12
