Question

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?

Answer 1

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

`A=(bh)/(2)`

The base is equal to 2x - 4

and

the height is equal to 2x - 4 also

So the area of the triangle will be :

`A=((2x-4)(2x-4))/(2)`

Multiplying the numerator using multiplication of two binomial terms :

1st step : Multiply the first
