Given the expression below

To find n
Open the brackets

Collect like terms

Since, the sides are not equal,
Hence, there is no solution
For this case we have that the area of the triangle is given by:

Where:
b: It's the base
h: It's the height
We have to:

The atura will be given by:

So, the area is:

Answer:
144
