Question

Find the area of the triangle.

The area of the triangle is _ (Simplify your​ answer.)

Answer 1

(6x² - 2x) in²

Explanation:

area of a triangle = ½(base×height)

= ½ (3x - 1) (4x)

= ½ (12x²- 4x)

= 6x² - 2x

Answer 2

`6x^2 - 2x` in²

Explanation:

Hello!

Area of a triangle:
`A = \frac12 b*h`

We can plug the equations into each variable to solve for the area.

Find the Area

• 
  `A = \frac12 b*h`
• 
  `A = \frac12 (3x-1)(4x)`
• 
  `A = \frac12(12x^2 - 4x)`
• 
  `A = 6x^2-2x`

The area of the triangle is 6x² - 2x in².
