The simplified form of the given expression will be 
<h3>How to simplify values which are under the root?</h3>
If possible, try to defactor what is inside the root.
For example, if 8 is under square root, then you can defactor 8 as made up of 2 times 2 times 2. Since 2 times 2 is perfect square, thus this can come out of the root.
Simply, some more such methods can be used to simplify these type of values.
<h3>Using the simplification method on given expression</h3>

Thus, after getting simplified, the expression becomes

When finding the area of a triangle, you always divide the product by 2 because a triangle is half a square.
Answer:
80 square units
Step-by-step explanation:
The area formula refers to a generic triangle ABC in which side lengths 'a' and 'b' are known and angle C is between those sides.
In the given figure, we have known side lengths of 12 and 14, and the angle between them is 72°.
Putting these numbers into the formula, we find the area to be ...
A = (1/2)(12)(14)sin(72°) ≈ 79.9 ≈ 80 . . . . square units
The area of the triangle is about 80 square units.
