The right triangle shown has two sides that are each 2x - 4 inches long.2x - 42x - 4The area of a triangle is A - bh, where b is the base and h is the height of the triangle. What is the area of the triangle shown?

Respuesta :

Note that the fomula for the area of a triangle is base x height divided by 2 :

[tex]A=\frac{bh}{2}[/tex]

The base is equal to 2x - 4

and

the height is equal to 2x - 4 also

So the area of the triangle will be :

[tex]A=\frac{(2x-4)(2x-4)}{2}[/tex]

Multiplying the numerator using multiplication of two binomial terms :

1st step : Multiply the first
