Question

How do you find the area of a triangle with base of 3x+5 ft and a height of 5x ft?

Answer 1

The area of the triangle will be `= color(green)(5/2*(3x^2+5x) sq. ft`

Explanation:

Area of a Triangle = `1/2*Base * Height`

We have been given the base as `3x+5` and the height as `5x`

Substituting the values in the formula, we get:

Area of a Triangle = `1/2*(3x+5) * 5x`

`= 5/2*(3x^2+5x)`

The area of the triangle will be `= color(green)(5/2*(3x^2+5x) sq. ft`
