Question

The height of a triangle is (2x - 4) and the base is3x^2- 2x +1. Find an expression for the area.

Answer 1

Given

The height of a triangle is (2x - 4) and the base is 3x^2- 2x +1.

Step-by-step explanation

The area of triangle is determined as

`A=(1)/(2)* b* h`

Substitute the value of base and height.

`\begin{gathered} A=(1)/(2)*(3x^2-2x+1)(2x-4) \\ A=(1)/(2)*(3x^2-2x+1)*2(x-2) \\ A=(3x^2-2x+1)(x-2) \end{gathered}`

Answer

The expression for the area is

`A=(3x^2-2x+1)(x-2)`
