3. The area of a triangle can be given by (just plug and chug as always):

The area of the triangle is
6ft².
4. I will divide into a triangle and a rectangle (because the actual equation for the area of a pentagon requires it to be a perfect pentagon). Let's do the triangle first (height is 3 because you subtract 12 from 15):


Now we just add them:

So, the area of that pentagon is
108m².
5. You are actually wrong on this one because the area of a triangle is:

So, just halve your answer and it will be correct.
6. We can just split it into 4 triangles of equal area and then multiply the area of 1 triangle by 4 to get the total area. Let's do just that:

Multiply by 4 to get total area:

So, the area of the given rhombus is
25cm².
6 divided by 6n equals 14
6/6n = 14 (6/6 = 1)
n = 14
Answer:
$ 32.95
Step-by-step explanation:
Cost of Stock at 2010= $ 50
Declining rate each year= 8%
We have to find cost of stock at 2015
Cost of stock after 5 years= $ 50 
Value of stock after 5 years= $ 50 
Value of stock after 5 years= $ 50 
Value of stock after 5 years= $ 32.95
Hence, the correct answer is $ 32.95
