Question

Find the area of a triangle whose height is 2x and base is 2x + 2.

Answer 1

Answer:
`2x^(2)+2x`

Explanation:

1. You must apply the formula for calculate the area of a triangle, which is shown below:

`Area=(base*height)/(2)`

2. You know the height and the base, which are given in the problem. Then, you only need to substitute them into the equation shown above and simplify it, as following:

`Area=(2x(2x+2))/(2)`

`Area=x(2x+2)\\Area=2x^(2)+2x`
